`n` small drops, each of radius `r` and having same charge `q` are combined to from a big drop. Find rato of capacitance, potential and stored energy in bigger drop and smaller drop.

Text Solution

AI Generated Solution

To solve the problem step-by-step, we will analyze the situation of combining `n` small drops into a larger drop and derive the ratios of capacitance, potential, and stored energy. ### Step 1: Determine the Radius of the Big Drop The volume of `n` small drops is equal to the volume of the big drop. The volume \( V \) of a sphere is given by: \[ V = \frac{4}{3} \pi r^3 \] ...
