A car is accelerated on a levelled road and attains a velocity 4 times of its initial velocity. In this process the potential energy of the car (a) does not change (b) becomes twice to that of initial (c) becomes 4 times that of initial (d) becomes 16 times that of initial

Answer is ‘does not change’

Potential energy is the product of height, mass and gravity. Hence height is a factor in determining potential energy. Here the height does not change. Therefore, potential energy of the car does not change.

So, the correct option is (a)
