Problem

A proton beam passes without deviation through a region containing uniform, transverse, mutually perpendicular electric and magnetic fields with

E=120\text{ kV/m}

and

B=50\text{ mT}

. The beam then strikes a grounded target. Find the force imparted by the beam on the target if the beam current is

I=0.80\text{ mA}
