Answer:
(a) A. Uniform line of charge and B. Uniformly charged sphere
(b) To three digits of precision:
λ = 1.50 * 10^-10 C/m
p = 2.81 * 10^-4 C/m^3
Explanation:
Answer:
Eo = 9.796 x 10^2 N/C
Bo = 3.266 x 10^-6 T
Explanation:
Given
Wavelength λ = 633 nm
Diameter of the beam D = 1.0 mm
Power P = 1.0 mW
Solution
Radius of the beam r = D/2 = 0.5 mm = 0.0005 m
Area of cross section
Intensity
Amplitude of Electric Field
Amplitude of Magnetic Field
Answer:
0.018kg
Explanation:
Q=mlf
m=?,Lf=334000J/kg,Q=5848J
5848=mx334000
5848=334000m
divide both sides by 334000
334000m/334000=5848/334000
m=0.018kg
