Three weights are hanging over a smooth fixed pulley as shown in the figure. What is the tension in the string connecting weights `B` and `C` ?

A

`g`

B

`g//9`

C

`8g//9`

D

`10g//9`

Text Solution

Verified by Experts

The correct Answer is:
D
`a=((5-4)/(5+4))g=(g)/(9)`
`T-mg=ma`

`T=m(g+a)`
`=1(g+(g)/(9))=(10g)/(9)`
