When a body is thrown up in a lift with a velocity `u` relative to the lift, the time of flight is found to be `t`. The acceleration with which the lift is moving up isA. `(u - g t)/(t)`B. `(2u - g t)/(t)`C. `(u + g t)/(t)`D. `(2u + g t)/(t)` |

Answer» Correct Answer - B `A_("rel") = (g + a)` Since `t = (2u)/(A_("rel"))` `rArr a = ((2u - g t)/(t))` |
