A particle moves in a region having a uniform magnetic field and a parallel, uniform electric field.

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...

(c) electromagnetic induction in the aluminium plate giving rise to electromagnetic damping.

(c) a helix with uniform pitch

The correct answer is (b) E= 0, B ≠ 0

(c) An electromagnetic wave may be passing through the region.

 (a) Balmer Series (b) Lymen Series (c) Pfund Series

r = 0.5cm = 0.5 × 10–2m B = 0.4T, E = 200V/m The path will straighten, if qE = quB => E = (rqB X B)/m  [∴ r = mv/qB] => E...

Since force is not constant for t>0 in the Z direction.So how you have used NLM.

(d) Tropical region
