Q72

Consider the following three independent cases: i. Particle A of charge +q moves in free space with a constant velocity v (v ≪ speed of light). ii. Particle B of charge +q moves in free space in a circle of radius R with same speed v as In case i. iii. Particle C having charge -q moves as in case ii. If the powers radiated by A, B and C are PA, PB and PC respectively then
