Paragraph for next 3 questions
A small spherical monoatomic ideal gas bubble (γ = 5/3) is trapped inside a liquid of density ρl (see figure). Assume that the bubble does not exchange any heat with the liquid. The bubble contains n moles of gas. The temperature of the gas when the bubble is at the bottom is T0, the height of the liquidis H and the atmospheric pressure is P0 (neglect surface tension).

Section: Physics

Question : 15 of 69

Marks: +1, -0

As the bubble moves upwards, besides the buoyancy force, the following forces are acting on it:

[JEE Adv 2008 P1]

Only the force of gravity.
The force due to gravity and the force due to the pressure of the liquid.
The force due to gravity, the force due to the pressure of the liquid and the force due to viscosity of the liquid .
The force due to gravity and the force due to viscosity of the liquid.
