Question

State whether true or false:
A boy throws a ball down from the second floor of a building. In this case, electrostatic force is acting on the ball.

  1. True
  2. False

A
False
B
True
Solution
Verified by Toppr

When boy throws a ball down only gravitational force will act, as electrostatic force act between two charge particle , so there is only gravitational force that is acting on ball.

Q5

Two boys were playing with the same ball on a level ground. One of the boys throws the ball on the third floor of the building which is at a height of 5 m and the other boy manages to throw on the fourth floor which is at a height of 7 m from the level ground. Then the ratio of the potential energy gained by the ball in both cases is:
