34: Magnetic Field
- #3Which 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++digAnsr: dAns : (d) Li++
Force on a moving charged particle,
F = qVBsin`` \theta ``
​As velocity V and magnetic field B are constant, and angle between the magnetic field and charged particle is `` 90°``, the only thing on which force F depends is charge q.
Now, the charge on `` L{i}^{++}`` > charge on electron, proton or `` H{e}^{+}``. So the force is maximum for `` L{i}^{++}``.
