Question

Three identical vessels A, B and C are filled with water, mercury and Kerosene respectively up to an equal height. The three vessels are provided with identical taps at the bottom of
the vessels. If the three taps opened simultaneously, then which vessel is emptied first?
a. Vessel B
b. All the vessels A, B and C will be emptied simultaneously
c. Vessel A
d. Vessel C

Answer 1

All the vessels will get emptied

Answer 2

The answer will the (d) vessel C. it is the jar of kerosene that will be emptied faster.

Kerosene is lighter the water and mercury hence will be more active by gravitational power.

Hence if let them fall (water, mercury, and kerosene) kerosene will fall down faster than the rest two jars.

As viscosity of the product kerosene is lesser than water and that is why the jar kerosene will be emptied fastest.
