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

38 N

B

40 N

C

36 N

D

30 N

Text Solution

Verified by Experts

The correct Answer is:
B
Tension is given by
`T = (2m_(1)m_(2))/(m_(1) + m_(2)+ m_(3)) xx g = (2 xx 6 xx 6 xx 10)/(6 + 6 + 6) = 720/18 =40`
