Two blocks of masses m(1) and m(2)(m(1) ...

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))`

Text Solution

Verified by Experts

The correct Answer is:
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)))`
