Question

A 4 mC charge has velocity $\bold u = 1.4 \bold a_x - 3.2 \bold a_y - \bold a_z m/s$ at point P(2, 5, -3) in the presence of $\bold E = 2xyz \bold a_x + x^2 z \bold a_y + x^2y \bold a_z V/m$ and $\bold B = y^2 \bold a_x + z^2 \bold a_y + x^2 \bold a_z Wb/m^2$ . Find the force on the charge at P.

Answer given: $-152.8 \bold a_x - 170.4 \bold a_y -189.6 \bold a_z mN$
