Answer 2

The friction force acting on the block is (3) 500N.

Given:

Force of 500N applied on a block of mass 5kg and coefficient of friction(u) = 0.2.

To Find:

Friction force acting on the block.

Solution:

To find the frictional force acting on the block we will follow the following steps:

The frictional force is the force acting on an object when one body moves over the surface of another body. Friction helps in motion. Due to friction, we can do our daily work.

From the above diagram of the block, we can say that the applied force is equal to the frictional force.

A total of four forces acting on the block are the force due to the weight of the block, normal reaction, friction, and applied force.

Applied force = Frictional force

Here, applied force = 500N

So,

Frictional force = 500N

Henceforth, the friction force acting on the block is 500N.
