An electron is projected into a magnetic field of flux density $10\, Wb/m^2$ with a velocity of $3 × 10^7\, m/s$ at an angle of 30° to the field. The magnetic force on the electron is: |
$1.6 × 10^{-11} N$ $4.8 × 10^{-11} N$ $2.4 × 10^{-11} N$ $9.2 × 10^{-11} N$ |
$2.4 × 10^{-11} N$ |
The correct answer is Option (3) → $2.4 × 10^{-11} N$ |
