A lift can move upward or downward. A light inextensible string fixed from ceiling of lift when a frictionless pulley and tensions in string `T_(1)`. Two masses of `m_(1) and m_(2)` are connected with inextensible light string and tension in this string `T_(2)` as shown in figure. Read the questionbs carefully and answer

If `m_(1)=m_(2) and m_(1)` is moving at a certain instant with velocity `v` upward with respect to lift and the lift is moving in upward direction with constant acceleration `(a lt g)` then speed of `m_(2)` with respect to lift :

A

` m_2g`

B

` 2m_1g`

C

`(m_1 + m_2)g`

D

zero
