A charge of 800 mu C is moving along the xaxis of the coordi

A charge of 8.00 mu C is moving along the x-axis of the coordinate system shown below with a constant speed of 3.00 Times 10^5 m/s. It enters a constant magnetic field 25T applied along the y-axis and a constant Electric Field of 7000 V/m applied along the +x direction. Determine the Force (magnitude and direction) exerted on the charge.

Solution

F=qvB+qE=q(vB+E)

we know 1 T=10⁴ gauss

F=8*10^-6(3*10⁵ *25*10⁴+7000)=600*10^-3 +56*10^-3 =656*10^-3 n/am
