A charge of 5 μC moves with a speed of $2 × 10^6 m/s$ along the positive y-axis. A magnetic field $\vec B$ of strength $(2\hat i +\hat k)T$ exists in space. The magnetic force acting on the charge is : |
$(-20\hat k + 10\hat i) N$ $(20\hat k - 10\hat i) N$ $(20\hat k + 10\hat i) N$ $(10\hat i + 5\hat k) N$ |
$(-20\hat k + 10\hat i) N$ |
The correct answer is Option (1) → $(-20\hat k + 10\hat i) N$ |
