Question

A block is placed on a rough horizontal surface.
A horizontal force is applied to move the block.
Then force required for pulling is same as that required
for pushing. why?

Answer 1

This is because pulling and pushing forces both are  applied on the same block just the direction is different.

If the force is constant for both push and pull , it is obvious that they will be equal.

Moreover the frictional force will also be the same.
