Question

when a body hanging from a spring balance is immersed in water it floats just below the surface of water and shows 100g loss in its weight . What is the weight of the body in water ? , what is weight of body in air ? , what is upthrust on body ? , what is volume of body ? Give reason for answer . Given : acceleeation due to gravity at place is 10 m s -2 , volume of 1g of water = 1mL

Answer 1

100g weight loss => bodies volume is 0.1l 

The weight of the body in water is zero. It has the same density as water. If it was less dense than water it would float and part of it would stick out of the water. If it was denser than water it would sink to the ground. 

Out of the water the body weighs 100g
