If \( n \) is an integer and \( Z = \cos \theta + i \sin \theta, \theta \neq (2n + 1)\frac{\pi}{2}, \) then: \[ \frac{1 + Z^{2n}}{1 - Z^{2n}} = ? \]
The electric field for an electromagnetic wave is given by \( E = 40 \sin(kz - 6 \times 10^8 t) \), where the magnitude of \( E_0 \) is in V/m.The magnitude of the wave vector \( k \) is
As shown in the figure, a surface encloses an electric dipole with charges \( \pm6 \times 10^{-6} \, {C} \). The total electric flux through the closed surface is:
