A V= 160-V battery is connected across two parallel metal plates of area 28.5 cm^2 and separation 8.50 mm. A beam of alpha particles (charge +2e, mass 6.64×10^−27kg) is accelerated from rest through a potential difference of 1.80 kV and enters the region between the plates perpendicular to the electric field, as shown in the figure.(Figure 1) Part A What magnitude of magnetic field is needed so that the alpha particles emerge undeflected from between the plates?
