Question

A solid floats with 1/5th of its volume above water. Find density of the solid. I'm from class 8​

Answer 1

Let the volume of the solid be” v “

Weight of the solid then is ,volume of water displaced(4v/5)* sp gravity of water1* gravitational accln.g.= 4v*1*g/5 unit

This weight of the new liquid will have volume of 4v*1*g/5*1.6g = 0.5v

So the solid will have 1/2 of its volume above the liquid.
