Question

A body attached to spring balance is put in water .The reading of spring balance a)decrease.b)increase c)may increase or decrease

Answer 1

When the body is attached to a spring balance and put in water, the reading shown in the spring balance decreases.

• The decrease in the weight is equal to the weight of the water displaced.
• This lose of weight is due to the buoyant force acting on the body by the water.
• This is due to the difference in pressure acting on body inside water.
• The bottom of the body is deeper in water resulting in an increased pressure than the top portion of the body.This results in buoyant force and loss of weight of the body
