Question

(50%) Problem 2: An oscillating EMF causes a particle with a net electric charge of 1.6 md to undergo constant uniform simple harmonic oscillation with an angular frequency of 3.5 x 106 rad/s and an amplitude of 2 cm. What is the average power (in W) radiated by the oscillating particle? Gra Ded avg

Answer 1

Ans: Given Q = 1.6 mC, $\omega$ = 3.5 x 10⁶ rad/s, A = 2 cm = 0.02 m

The average power by an oscillating charge is given by Larmour's formula and is
