Two masses of 1 kg and 5 kg are attached to the ends of a massless string passing over a pulley of negligible weight. The pulley itselt is attached to a light spring balance as shown in figure. The masses start moving during this interval, the readcing of spring balance will be-

A

More than 6 kg

B

Less than 6 kg.

C

Equal to 6 kg.

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
B
as motionis also happeing
`therefore` net force on pulley by string is less than 6g.
