Explanation / Answer

Part A:

Relation between intensity and electric field is given by:

I = e0*c*E0^2/2

I = 50 uW/m^2 = 50*10^-6 W/m^2

Using given values:

E0 = sqrt (2*I0/(e0*c))

E0 = sqrt (2*50*10^-6/(8.85*10^-12*3*10^8))

E0 = 0.194 N/C

Part B

relation b/w magnetic field and electric field is

E = c*B

B = 0.194/(3*10^8)

B = 6.47*10^-10 T

Part C

Intensity = Power/Area

P = I*A

A = surface area of hemisphere = 2*pi*R^2

P = I*2*pi*R^2

P = 50*10^-6*2*pi*6000^2

P = 11309.73 W
