A beam of protons passes undeflected with a horizontal velocity v, through a region of electric and magnetic fields, mutually perpendicular to each other and normal to the direction of the beam. If the magnitudes of the electric and magnetic fields are 50 kV/m and 100 mT respectively ; calculate the (i) velocity v of the beam. (ii) force with which it strikes a target on the screen, if the proton beam current is equal to 0.80 mA.
