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

go down

go up

maintain same height

sink to bottom

Text Solution

Verified by Experts

The correct Answer is:

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.

By considering the dynamics of a thin "cylinder" of water in the steam answer the following: (ignore any reistance to the flow and any effects of surface tansion, given rho_(w) = density of water) A student observes after setting up this experiment that for a tap with D_(0) = 1 cm at x = 0.3 m the stream diameter D = 0.9 cm . The heights b of the water above the tap in this case will be:
