railway RRB Technician Grade 1 Mock Test 2024 Physics Moving Charges and Magnetism Motion in a Magnetic Field
A charge particle of mass 'm' and charge 'q' is moving with a speed 'v' in a magnetic field B. If the radius of the circular path traced by a charge particle is 'r'. Then find the ratio of q/m.
1
\(\frac{q}{m}=\frac{v}{Br}\)
2
\(\frac{q}{m}=\frac{vB}{B}\)
3
\(\frac{q}{m}=\frac{vr}{B}\)
4
\(\frac{q}{m}=\frac{B}{vr}\)
