An electron experiences a force of `2.4 xx 10^(-13)` N when it enters a magnetic field with a velocity of `10^6 ms^(-1)` at an angle of `30^@`. What is the flux density ?

Explanation

To find the magnetic flux density (B) experienced by the electron, we can use the formula for the magnetic force acting on a charged particle moving in a magnetic field:

\[ F = q v B \sin(\theta) \]

Where:
- \( F \) is the magnetic force (given as \( 2.4 \times 10^{-13} \, \text{N} \)),
- \( q \) is the charge of the electron (\( 1.6 \times 10^{-19} \, \text{C} \)),
- \( v \) is the velocity of the electron (\( 10^6 \, \text{m/s} \)),
