Q. 34.5( 4 Votes )

Which of the following particles will experience maximum magnetic force (magnitude) when projected with the same velocity perpendicular to a magnetic field?
A. Electron

B. Proton

C. He+

D. Li++

Answer :

Here the particle is experiencing a maximum magnetic filed and projected with a same velocity. There are no variations in the both. So both magnetic field and velocity are constant over here.

Formula used: The magnetic force is given by



Where F is magnetic force


q is electric charge =


v is velocity


is angle between magnetic field and a charge


In the above equation magnetic field and velocity are constant. So force will depend on the charge. In the option given Li++ has the highest charge. After Li++, He+ has highest charge. So Li++ will experience a maximum magnetic field.
