Three equal weights of mass 2 kg each are hanging on a string passing over a fixed pulley as shown in fig What is the tension in the string connecting weights B and C?

A

Zero

B

6.6N

C

3.3N

D

19.6N

Text Solution

Verified by Experts

The correct Answer is:
B
`a=(2g)/(3)`
for C `2g-T=2xx(2g)/(3)`
`T-2g-(2)/(3)xx2g=(2g)/(3)=(20)/(3)=6.6N`
