`He^(2+)` ion travels at right angles to a magnetic field of `0.80 T` with a velocity of `10^5 m/s`. Find the magnitude of the magnetic force on the ion.

Explanation

To find the magnitude of the magnetic force on a `He^(2+)` ion traveling at right angles to a magnetic field, we can use the formula for the magnetic force:

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Magnetic field strength (B) = 0.80 T (Tesla)
- Velocity of the ion (v) = \(10^5 \, \text{m/s}\)
- Charge of the helium ion (He^(2+)) = +2 times the charge of an electron.
