A 120V battery is connected across two parallel
A 120V battery is connected across two parallel metal plates of area 28.5cm2 and separation 7.20mm A beam of alpha particles (charge +2e, mass 6.641027kg ) is accelerated from rest through a potential difference of 1.75kV and enters the region between the plates perpendicular to the electric field, as shown in (Figure 1). Figure 1 of 1 What magnitude of magnetic field is needed so that the alpha particles emerge undeflected from between the plates? Express your answer with the appropriate units.
