Soap bubble of radius R is blown at one end of a pipe of circular of circular cross-section of radius R as shown in diagram. On the vertical portion of pipe, there is a piston of mass m. T is surface tension of liquid.

Find the mass of piston for which it remain in equilibrium

Soap bubble of radius R is blown at one end of a pipe of circular of circular cross-section of radius R as shown in diagram. On the vertical portion of pipe, there is a piston of mass m. T is surface tension of liquid. If piston is slightly displaced in downward direction, then its acceleration when radius of bubble grows to 2R is
