A body is projected vertically upwards. At its highest point it explodes into 2 pieces of masses in the ratio 2:3 and the lighter piece flies horizontally wih a velocity of 6metre per second.The time after which the lines joining the point of explosion to the position of particlesd are perpendicular to each other is(g=10m/ssq.)?
