Question

The magnetic field of a plane electromagnetic wave is given by : vector B = B₀ i[cos(kz - ωt )] + B₁ j cos (kz + ωt)

Where B₀ = 3 x 10^–5 T and B₁ = 2 × 10^–6 T. The rms value of the force experienced by a stationary charge Q = 10 ^–4 C at z = 0 is closest to -

(1)   0.6 N 

(2)  3 x 10^–2 N 

(3)   0.9 N

(4)   0. 1 N 

Answer 1

Correct option  (1) 0.6 N

Explanation:

Maximum Electric Field = BC
