What is the magnetic force acting on a proton (charge $+1.6 × 10^{-19}C$) moving at an angle of 30° across a magnetic field of $5.3 × 10^{-3} T$ at a speed of $3.0 × 10^5 m s^{-1}$? |
$1.272 × 10^{-19} N$ $1.3 × 10^{-16} N$ $1.272 × 10^{16} N$ $2.2 × 10^{-16} N$ |
$1.3 × 10^{-16} N$ |
The correct answer is Option (2) → $1.3 × 10^{-16} N$ |
