Question

When a charged particle enters perpendicular to uniform magnetic field, path followed by it is
(D) parabolic
1A) linear
(C) helical
(B) circular
dicular​

Answer 1

Answer:

When a charged particle enters a magnetic field at a direction perpendicular to the direction of motion, the path of the motion is circular. In circular motion the direction of velocity changes at every point (the magnitude remains constant). Therefore, the tangential momentum will change at every point.
