railway RRB Technician Grade 1 Mock Test 2024 Physics Moving Charges and Magnetism Motion in a Magnetic Field
A charged particle falls perpendicularly into a uniform magnetic field and traces a circular path. The relationship between radius r of the circular path and KE of the particle is given as-
1
r ∝ KE2
2
r ∝ KE-1
3
r2 ∝ KE3
4
r ∝ \(\sqrt{KE}\)
