The magnetic field of a plane electromagnetic wave is given by : vector B = B_{0} i[cos(kz - *ω*t )] + B_{1} j cos (kz + *ω*t)

Where B_{0} = 3 x 10^{–5} T and B_{1} = 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
