Three equal weight A,B and C of mass 2kg...

Three equal weight `A,B` and `C` of mass `2kg` each are hanging on a string passing over a fixed frictionless pulley as shown in the figure. The tension in the string connecting weights `B` and `C` is approximately

A

Zero

B

13 N

C

`13.3` N

D

`19.6` N

Text Solution

Verified by Experts

The correct Answer is:
B
`4g -2g -6a implies a=g//3`
`20-T= (2g)/(3)implies 20- (2g)/(3) =T`
`implies13.3N =T`
