Two mutually perpendicular forces are acting on a moving object. One force acts in the direction of motion of the object and the other force acts perpendicular to the direction of motion. During this interval, the kinetic energy of the body changes from 25 J to 100 J and the direction of motion is unaffected. The work done by the force acting perpendicular to the direction of the motion is:

During this interval, the kinetic energy of the body changes from 25 J to 100 J and the direction of motion is unaffected. The work done by the force acting perpendicular to the direction of the motion is:
The correct option is B 0 J
The force acting perpendicular to the direction of motion produced no displacement and so the work done by this force is zero.
In the above question, the kinetic energy will increase only due to the force acting in the direction of motion or velocity of the object. The force acting perpendicular to the direction of motion has no contribution in the increase of kinetic energy and hence it does no work.
