Correct Answer : Option (C) : 35.36pF
Explanation : The capacitance of any material is given by, C = εA/d, where ε = εoεr is the permittivity in air and the material respectively. Thus C = 1 X 8.854 X 10-12 X 20/5 = 35.36pF.
Correct Answer : Power radiated per unit solid angle in that direction
Correct Answer : A quarter wave line
Correct Answer : Larger wavelength than in the free space
