Question

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. $H{e}^{+}$
• D. $L{i}^{++}$

Answer 1

The correct option is D $L{i}^{++}$

F=qvB

As velocity and magnetic field are constant for all the given 4 options

F depends on charge value

For electron, proton and He${}^{+}$ q=1

For Li${}^{++}$ q=2

So Li${}^{++}$ experiences maximum force
