Q. Two bodies are projected from ground with same speeds $40\, ms ^{-1}$ at two different angles with respect to horizontal. The bodies were found to have same range. If one of the body was projected at an angle of $60^{\circ}$, with horizontal then sum of the maximum heights, attained by the two projectiles, is ____$m$. (Given $g=10 \,ms ^{-2}$ )
Solution:
