Two persons `P` and `Q` of same height are carrying a uniform beam of length `3m`. If `Q` is at end, the distane of `P` from the other end so that `P,Q` receive loads in the ratio `5:3` is

A

`0.5 m`

B

`0.6 m`

C

`0.75 m`

D

`1m`

Text Solution

Verified by Experts

The correct Answer is:
B
Let `x` is distance of `P` from other end
`(xF_(P))+(LF_(Q))=WL/2`
Where `L` is the length of the rod and `W` is its weight but `W=F_(P)+F_(Q)`
