If an electron moves at velocity of \( 10^{6} \mathrm{~ms}^{-1} \) in a uniform magnetic field of \( 10^{5} \) gauss making an angle of \( 30^{\circ} \) with the field, find the force acting on the electron.
A \( 8 \times 10^{-9} \mathrm{~N} \)
B \( 1.6 \times 10^{-8} \mathrm{~N} \)
C \( 1.6 \times 10^{-12} \mathrm{~N} \)
D \( 8 \times 10^{-13} \mathrm{~N} \)
Solution
Correct Answer: Option D
