thank u in advance

A charged particle, A, moving at a speed much less than c, decelerates uniformly. A second particle, B, has one-half the mass, twice the charge, three times the velocity, and four times the acceleration of particle A. According to classical electrodynamics, the ratio PB/PA of the powers radiated is
(A) 16
(B) 32
(C) 48
(D) 64
(E) 72
