At a certain height a shell at rest explodes into two equal fragments one of the fragments receives a horizontal velocity `u`.The time interval after which the velocity vectors will be inclined at `120^(@)` to each other is

At a certain height a body at rest explodes into two equal fragments with one fragment receiving a horizontal velocity of 10ms^(-1) . The time interval after the explosion for which the velocity vectors of the two fragments become perpendicular to each other is (g=10ms^(-2))

At a certain height a body at rest explodes into two equal fragments with one fragment receiving a horizontal velocity of 10ms^−1. The time interval after the explosion for which the velocity vectors of the two fragments become perpendicular to each other is
