1.	A particle is projected with velocity2sqrt(gh)so that it just clears two walls of equal height h which are a distance 2 h from each other. The time interval for which the particle travels between this two walls is(theta=60^(@))
Answer» `2 sqrt(H/g)` `sqrt(h/g)` `sqrt((2H)/(g))` `sqrt((h)/(2G))` Answer :A
