A body weight 20 N in water and 30 N in ...

A body weight 20 N in water and 30 N in a liquid. The actual weight of the body is 40 N, then find the specific gravity of the liquid.

Text Solution

Verified by Experts

Weight of the body in air `W_(1)=40 N`
Weight of the body in liquid `W_(3)=30 N`
Weight of the body i9n water `W_(2)=20 N`
Specific gravity of the liquid `=(W_(1)-W_(3))/(W_(1)-W_(2))=(10)/(10)=0.5`
