Two balls are dropped from different heights at different instants. Second ball is dropped $2$ seconds after the first ball. If both balls reach the ground simultaneously after $5$ seconds of dropping the first ball, then the difference between the initial heights of the two balls will be $(g = 9.8 {ms}^{- 2})$
