A force F is applied on block A of mass ...


A force F is applied on block A of mass M so that the tension in light string also becomes F when block B of mass m acquires an equilibrium state with respect to block A. find the force F. Give your answer in terms of m, M and g.

A

6 cm

B

5 cm

C

7 cm

D

8 cm

Text Solution

Verified by Experts

The correct Answer is:
A

Weight= upthrust from mercury + upthrust from water
`therefore " " 10xx8.56=(x xx 13.6)+(10-x)xx10`
Here x= depth inside mercury
Solving, we get
x=6 cm
