In the figure, a smooth pulley of negligible weight is suspended by a spring balance. Weights of 1 kg and 5kg are attached to the opposite ends of a string passing over the pulley and move with an acceleration due of gravity. During their motion, the spring balance reads a weight of

A

6 kg

B

less than 6 kg

C

more than 6 kg

D

may be more or less than 6kg

Text Solution

Verified by Experts

The correct Answer is:
B
`m_(1)g-T=m_(1)a, T-m_(2)g=m_(2)a, T^(1)=2T`
