A radio wave has a maximum magnetic field induction of 10-4 T on arrival at a receiving antenna. The maximum electric field intensity of such a wave is? (1) Zero (2) 3 × 104 V/m (3) 5.8 × 10-9 V/m (3) 3.3 × 10-13 V/m

Answer: (2) 3 × 10V/m

Given

E0 = cB0

  • c =  3 × 108
  • B= 10-4

E0  = 3 × 108 × 10-4

E0 =  3 × 10 Vm–1
