Two balls of mass `M` and `2M` are thrown horizontally with the same initial velocity `v_(0)` from top of a tall tower and experience a drag force of `-kv(kgt0)`, where `v` is the instantaneous velocity. Then

A ball is thrown upward with an initial velocity V_0 from the surface of the earth.The motion of the ball is affected by a drag force equal to mgammav^2 (where m is mass of the ball, v is its instantaeous velocity and gamma is a constant).Time taken by the ball to rise to its zenith is :
