270007 A bodyis projected vertically upwards. At its highest point it explodes into two pieces of masses in the ratio of 2:3 and the lighter piece flies horizontally with a velocity of \(6 \mathrm{~ms}^{-1}\). The time after which the lines joining the point of explosion to the position of particles are perpendicular to each other is
270010 From the top of a tower\(40 \mathrm{~m}\) high a ball is projected upwards with a speed of \(20 \mathrm{~m} \mathrm{~s}^{-1}\) at an angle \(30^{\circ}\) with the horizontal. The ratio of the total time of flight to hit the ground to the time taken by it to come back to the same initial elevation is \(\left(\mathrm{g}=10 \mathrm{~ms}^{-2}\right)\)
