Question

A positive charge of 1.5 µC is moving with a speed of 2 x 10^-6 ms^-1 along the positive X-axis. A magnetic field,\(\vec B\) = (0.2 \(\hat j\) + 0.4 \(\hat k\)) tesla acts in space. Find the magnetic force acting on the charge

Answer 1

Here q = 1.5 µC = 1.5 x 10^-6C

Magnetic force on the positive charge is
