Physics · JEE | Moving Charges and Magnetism

An electron moves with velocity \( v = 3 \times 10^6 \text{ m/s} \) along the \( x \)-axis in a uniform magnetic field \( B = (2 \hat{j} + 3 \hat{k}) \text{ T} \). The magnitude of the magnetic force acting on the electron is approximately:

1. A
   \( 1.6 \times 10^{-12} \text{ N} \)
2. B
   \( 2.4 \times 10^{-12} \text{ N} \)
3. C
   \( 4.8 \times 10^{-13} \text{ N} \)
4. D
   \( 3.2 \times 10^{-13} \text{ N} \)
