Dipole moment of the system, p = q × dl = −10−7 C m
Rate of increase of electric field per unit length,
dE/dl=105 NC−1
Force (F) experienced by the system is given...
(c) : Magnetic field applied parallel to motion of
electron exerts no force on it as θ = 0 and force = Bevsinθ = zero
Electric field opposes motion of electron which...
All of these
EXPLANATION:
Consider a thin spherical shell and choose r = infinity where potential is zero. At infinity V = 0, E = 0. So (a) is true. At any point outside...
(b) have zero average value
(c) are perpendicular to the direction of propagation of light.
(d) are mutually perpendicular.
EXPLANATION:
The electric and magnetic fields vary with time and position, hence (a) is...
Potential energy of a charge q in an external electric field is defined as the work-done in bringing the charge q from infinity to a distance r in an external...
