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 newton

C

3.3 newton

D

19.6 newton

Text Solution

Verified by Experts

The correct Answer is:
b
a = Net force/total mass ` = 2g//5 = g//3` For C< upward force in T< downward force is 2g, `2g -T =2 xx 9, T = 4g//3`
