A helium ion `(He)^(2+)` travels at right angles to a magnetic field of intensity 1.2T with a velocity of `2 xx 10^7 cms^(-1)`. Find the magnitude of the force acting on the ion.

Explanation

To find the magnitude of the force acting on a helium ion \((He)^{2+}\) traveling at right angles to a magnetic field, we can use the formula for the magnetic force on a charged particle:

\[ F = qvB \sin \theta \]

Where:
- \(F\) is the magnetic force,
