Question:medium

The number of turns of two circular coils A and B are 300 and 200 respectively. The magnetic moments of the two coils A and B are in the ratio 1:2. If the two coils carry equal currents, then the ratio of radii of coils A and B is

Show Hint

When dealing with ratios, set up the formula for the quantity in question and then write the ratio of the two cases. Cancel out any quantities that are constant or given to be equal. This simplifies the problem to an algebraic equation for the unknown ratio.
