A spherical bubble inside water has radius R. Take the pressure inside the bubble and the water pressure to be 𝑝0. The bubble now gets compressed radially in an adiabatic manner so that its radius becomes (𝑅−𝑎). For 𝑎≪𝑅 the magnitude of the work done in the process is given by (4𝜋𝑝0𝑅2𝑎)X, where X is a constant and . The value of X is________.
Magnitude of work done
So,
