The correct option is **A** 2 N

Given horizontal force F=10 N and coefficient of friction between block and wall μ=0.2

So the friction force will be, Ffr=0.2×10=2 N

As the block is in rest, ∑Fx=0,

Ffr.=mg=2 N

## FAQs

### Is a horizontal force of 10N necessary to just hold a block stationary against the wall? ›

Hence the correct option is C. A horizontal force of 10N is necessary to just hold a block stationary against a wall. **The coefficient of friction between the block and the wall is 0.2**.

**Is a horizontal force of 10N applied on a block? ›**

A horizontal force of 10 N is applied to a block of mass 2 kg resting on a rough horizontal table. Then normal force applied on the block by the table is **g = 10 m / s 2**.

**What is a horizontal force of 10 Newton is required to maintain a velocity of 2 meters per second? ›**

Since the question describes a horizontal force and a plane surface, we assume the direction of movement is completely aligned with direction of force applied. 60 (seconds) * 2 (m/s) = 120 metres. 120 (meters) * 10 N = 1200 Newton-metres or **1200 joules or 1.2 kj**.

**Is horizontal force of 25 Newton is necessary to just hold a block stationary? ›**

Given horizontal force F = 25 N and coefficient of friction between block and wall (μ)=0.4. We know that at equilibrium horizontal force provides the normal reaction to the block against the wall. Therefore, **normal reaction to the block (R) = F= 25 N**.

**What is the work done when you apply a 10n force on a wall? ›**

there will be **no work done** when you apply 10 Newton of force on wall. because in this case the displacement is zero. work done =force x displacement . but there is zero displacement so that the work done is zero.

**What happens if a block remains stationary in spite of a horizontally applied force? ›**

A stationary block remains stationary even after applying a horizontal force. This means that **frictional force is applied force**.

**What is the horizontal component of a force of 10n? ›**

FH=10 sin30 =10×12 =**5 N**.

**What will be the horizontal component of a force of 10 Newton is making an angle of 30 degree? ›**

F y = 10 N sin 30 ∘ F y = 10 N × 0.5 F y = **5 N** .

**What is the component of a force of 10 N in a direction perpendicular to it? ›**

The component of any vector in a direction perpendicular to its own is **zero**. As Force is a vector, the same holds true for it as well. So the answer is zero.

**How long will it take a force of 10 N to stop a mass of 2.5 kg? ›**

Expert-Verified Answer

We have to find, time (t) = ? Therefore, the object will take **5 sec** to stop a mass of 2.5 kg which is moving at 20m/s.

### What is a force of 10 Newton act on a body of 2 kg? ›

Solution: A force of 10 N acts on a body of 2 kg at rest for 3 seconds. **The kinetic energy acquired by the body in 3 seconds will be 225 J**.

**What is required for a horizontal force of 490 Newton? ›**

The correct Answer is:0.083

Step by step video, text & image solution for A horizontal force of 490 N is required **to slide a sledge weighing 600 kg f over a flat surface**. Calculate the coefficient of friction. by Physics experts to help you in doubts & scoring excellent marks in Class 11 exams.

**What is a horizontal force of 750n is needed to overcome? ›**

A horizontal force of 750 N is needed to overcome **the force of static friction between a level floor and a 250-kg crate**.

**What is the minimum horizontal force? ›**

The minimum horizontal force that is applied to box to slide is always **equal to the frictional force**. The reason is that if the applied force is less than the friction force, then the box does slide. So, the minimum horizontal force applied to the box is computed as: F min = F = 31.8 N.

**What is the average force necessary to stop a hammer with 25 Newtons? ›**

The average force that is necessary to stop a hammer with 25 Newton-sec momentum in 0.05 sec, expressed in Newtons is. **500**.

**Do you need a force to sustain horizontal motion? ›**

If the object is moving in a horizontal motion, it will continue due to inertia until any force is applied. So, **it is not necessary to sustain any horizontal motion**. Hence, it can be concluded that the force is not necessary to sustain horizontal motion due to the inertia of the matter.

**Are horizontal forces required to keep a projectile moving horizontally? ›**

Defining Horizontal Motion

Since there are no horizontal forces, the projectile continues to move at a constant horizontal velocity. This means that **horizontal forces are not required to keep a projectile moving horizontally**. The horizontal motion of a projectile is independent of its vertical motion.

**What is the force required to move a stationary object? ›**

If there is a friction force between the object and the ground then the friction force will oppose the motion of the object. Hence, **the stationary object will move only if the applied force is greater than the friction force between the object and the ground**.

**What is the support force on a 10n book that rests on a horizontal surface? ›**

The support force on a 10 N book that rests on a horizontal surface is. **10 N**. The net force of an object is. the combination of all forces acting on it.
