Question

(1396) Problem 6: A particle of charge q enters a region with a uniform magnetic field perpendicular to its velocity and follows a circular path. If this particle carried a charge 2a, the radius of circular path will be Half of radius of particle Four times radius of particle Twice of the radius of particle Grade Summary Deductions Potential 0% 100% Submissions Attempts i (25% per attempt) detailed view O ¼ of radius of particle Same as for particle Submit Hint I give up! Hints: -deduction per hint. Hints remaining: 2 Feedback: 200-deduction per feedback.

Explanation / Answer

We know

mv2/r = qvB

r=mv/qB

if the particle had charge 2q, radius will be half of radius of particle with charge q

correct option is 1st option
