A charged particle with charge to mass ratio `((q)/(m)) = (10)^(3)/(19) Ckg^(-1)` enters a uniform magnetic field `vec(B) = 20 hat(i) + 30 hat(j) + 50 hat(k) T` at time t = 0 with velocity `vec(V) = (20 hat(i) + 50 hat(j) + 30 hat(k)) m//s`. Assume that magnetic field exists in large space. During the further motion of the particle in the magnetic field, the angle between the magnetic field and velocity of the particleA. remains constantB. increasesC. decreasesD. may increase or decrease |
|
Answer» Correct Answer - A Angle remains constant, because magnitudes of components of velocites along and perpendicular to magnetic field remain constant. |
