A tank filled with water has two taps to exhaust and pour. A hollow sperical ball is half submerged in water. Through one tap, water is taken out and through another tap, a liquid of density double the density of water is poured in tank such that volume of liquid in tank remains constant. Sphere will

A

go down

B

go up

C

maintain same height

D

sink to bottom

Text Solution

Verified by Experts

The correct Answer is:
B
W=Upthrust `=V_(i)rho l g " or" V_(i)=(W)/(rho l g)`
If density of liquid `rho l` is increased, immersed volume `V_(i)` will decrease or the ball will go up.
