Homework Equations


E=100 kV/m E=cB
B = E/c B=(100000/2.998*10^8) B=0.0003335557
m = 10g = 0.01kg A=0.5mm^2 = 5*10^-7 m^2

I = (EB)/(4п*10^-7) = (100000)(0.0003335557) / (4п*10^-7)
I = 26543519.23

The Attempt at a Solution


a) Pressure = I/c = (26543519.23 )/(2.998*10^8)
Pressure = 0.08853742237 N/m^2
b)
Power = IA
a = Power/cm = IA/cm
a = (26543519.23 )(5*10^-7) / (2.998*10^8)(0.01)
a = 0.00000442687
