A body weight 40 g in air. If its volume is 10 `cm^3`, in water it will weigh:

A

`30` g

B

`40` g

C

`50` g

D

data insufficient

Text Solution

Verified by Experts

The correct Answer is:
A
Loss of weight in water is equal to buoyant force.
Loss of weight = Bouyant force= weight of the water displaced by immersed volume
= Vdg
= `10xx1xxg=10` g
Weight in water= weight in air - loss weight in water = `40g-10g`
= `30` g
