Question

part a already solved.

A satellite 550 km above the earth's surface transmits sinusoidal electromagnetic waves of frequency 92.2 MHz uniformly in all directions, with a power of 25.0 kW.

Answer 1

B)

Electric field, E = sqrt(2 I/e0 c)

E = sqrt(2 x 6.58 x 10^-9/8.85 x 10^-8 x 3 x 10^8)

E = 2.23 x 10^-3 N/C

C)

Magnetic field, B = E/c = (2.23 x 10^-3)/(3 x 10^8) = 7.42 x 10^-12 T

D)

Force, F = (6.58 x 10^-9/3 x 10^8)(0.15 x 0.45) = 1.48 x 10^-18 N
