A non-relativistic proton beam passes without deviation

Question

A non-relativistic proton beam passes without deviation through the region of space where there are uniform transverse mutually perpendicular electric and magnetic fields- with E=120kV/m and B=50mT. Then the beam strikes a grounded target. Find the force with which the beam acts on the target if the beam current I=0.80mA
