Answer 2

Explanation:

According to work energy theorem the work done by the force is equal to increase in the kinetic energy of the body.

=>If the kinetic energy of the body increases then work is positive and if the kinetic energy decreases work is negative.Work done by conservative forces to move a particle in closed path is zero. Also, work done by nonconservative forces may be zero
