Question

A solid of weight 22N is dipped in water if the weight of the solid in water is 20N what is the relative density of solid

Answer 1

Sorry do not know .I will try in next question.

Answer 2

11

s is relative density of solid

s*d*g*v=22

d = density of water

v = volume of displaced liquid

weight of water displaced=22-20=2=d*g*v

so put this value in above equation
