A block of mass `m` is pulled by a uniform chain of mass `m` tied to it by applying a force `F` at the other end of the chain.The tension at a point `P` which is at a distance of quarter of the length of the chain from the free end,will be

A

`(3F)/4`

B

`(7F)/8`

C

`(6F)/7`

D

`(4F)/5`

Text Solution

Verified by Experts

The correct Answer is:
