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

1 m

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)`
