Work done in increasing the size of a soap bubble from a radius of 3 cm to 5 cm is nearly (surface tension of soap solution = 0.03 Nm^-1

Q. The surface tension of soap solution is $T=0.03{\text{Nm}}^{-1}$. If the size of a soap bubble is increased from a radius of $3\text{cm}$ to $5\text{cm}$, the work done in increasing the size of the soap bubble is

Q. Work done in increasing the size of a soap bubble from a radius of $3cm$ to $5cm$ is nearly (Surface tension of soap solution $=0.03$ $N{m}^{-1}$):

Q. The surface tension of soap solution is $T=0.03{\text{Nm}}^{-1}$. If the size of a soap bubble is increased from a radius of $3\text{cm}$ to $5\text{cm}$, the work done in increasing the size of the soap bubble is

Q. Calculate the work done in increasing the radius of a soap bubble in air from $1cm$ to $2cm$. The surface tension of soap solution is $30dyne/cm$. ($\pi =3.142$)
