One elite question every week. Crack it, share it, own it.
A non-conductive transparent liquid contains an air bubble. Charge is supplied to the bubble at dq/dt = 5 C/s, causing it to expand at dr/dt = 3 cm/s, where r is the radius of curvature of the bubble acting as an equi-convex lens. The bubble maintains a constant surface charge density σ = 5/π C/m², and the refractive index gradient of the liquid is dμ/dr = 6/200 m⁻¹. Find the refractive index of the liquid when the rate of change of focal length with respect to radius of curvature is unity (df/dr = 1).
