Solution

The correct option is A
Opposite to the direction of the applied force.

Friction has a tendency to oppose relative motion. As the block has a tendency to move towards right because of the applied force, friction will act towards left, i.e., opposite to the applied force.

Q. Multiple correct answers type
A 3-kg block of wood is on a level surface where

μ_{s} = 0.25

and

μ_{k} = 0.2

. A force of 7 N is being applied horizontally to the block. Mark the correct statement(s) regarding this situation.
a. If the block is initially at rest, it will remain at rest and friction force will be about 7 N.
b. If the block is initially moving, then it will continue its motion forever if the force applied is in the direction of the motion of the block.
c. If the block is initially moving and the direction of applied force is same as that of motion of block, then block moves with an acceleration of

1 / 3 m s^{- 2}

along its initial direction of motion.
d. If the block is initially moving and direction of applied force is opposite to that of initial motion of the block, then the block decelerates, comes to a stop, and starts moving in the opposite direction.
