Answer:Twice
Explanation:
It is given that car is raised on a lift with respect to ground.
Suppose car is raised by a height of h m from ground having mass m so gain in Potential Energy by car is
Gain in
Now if it were raised twice as high,i.e. 2 h height from ground then gain in Gravitational Potential Energy
It is clear that
Thus in second case gain in Potential Energy is twice as compared to first case
