CUET and UG exam CUET UG 2025 Mock Test Series Physics Moving Charges and Magnetism Motion in a Magnetic Field
An electron and a proton enter a region of uniform magnetic field in a direction at right angles to the field with the same kinetic energy. They describe circular path of radius re and rp respectively then
1
re = rp
2
re > rp
3
re < rp
4
re may be less than or greater than rp depending on the direction of the magnetic field.
