Ans. value of g on hills is less than that of plains.
 
Explanation: The height to which the ball bounces when thrown with velocity u is given by:
h = u2 / 2g.
The height to which the ball bounces is inversely proportional to the acceleration due to gravity at the place. Since the value of g on hills is less than that of plains, therefore it bounces higher on hills.
