Two blocks of masses `m_(1)` and `m_(2)(m_(1) gt m_(2))` are connected by a massless threads, that passes over a massless smooth pulley. The pulley is suspended from the ceiling of an elevator. Now the elevator moves up with uniform velocity `v_(0)` Now, select the correct options: A. Magnitude of acceleration of `m_(1)` with respect to ground is greater than `((m_(1)-m_(2))g)/(m_(1)+m_(2))`B. Magnitude of acceleration of `m_(1)` with respect to ground is equal to `((m_(1)-m_(2))g)/(m_(1)+m_(2))`C. Tension in the thread that connects `m_(1)` and `m_(2)` is equal to `(2m_(1)m_(2)g)/(m_(1)+m_(2))`D. Tension in the thread that connects `m_(1)` and `m_(2)` is greater than `(2m_(1)m_(2)g)/(m_(1)+m_(2))` |

Answer» Correct Answer - B::C The acceleration of the lift is zero `:.a=((m_(1)-m_(2))g)/((m_(1)+m_(2)))` `T=(2m_(1)m_(2)g)/((m_(1)+m_(2)))` |
