A 160-V battery is connected across two parallel metal plates of area 28.5 cm^2 and separation 8.10 mm . A beam of alpha particles (charge +2e, mass 6.64×10^−27kg) is accelerated from rest through a potential difference of 1.60 kV and enters the region between the plates perpendicular to the electric field.
Part A: What magnitude of magnetic field is needed so that the alpha particles emerge undeflected from between the plates?
Part B: What direction of magnetic field is needed so that the alpha particles emerge undeflected from between the plates if the charges are moving to the right and the electric field points upward?

A 150-V battery is connected across two parallel metal plates of
area 28.5 cm2 and a separation of 8.20 mm. A beam of
alpha particles (charge +2e, mass 6.64E-27 kg) is accelerated from
rest through a potential difference of 1.75 kV and enters the
region between the plates perpendicular to the electric field.
What magnitude and direction
of magnetic field are needed so that the alpha particles emerge
undeflected from between the plates?

Two parallel, metal plates with separation distance d = 1.00 cm
carry charges of equal magnitude but opposite sign. The plates are
oriented horizontally. Assume the electric field between the plates
is uniform, and it has a magnitude of 1,880 N/C. A charged particle
with mass 2.00 ✕ 10−16 kg and charge 1.07 ✕ 10−6 C is projected
from the center of the bottom negative plate with an initial speed
of 1.08 ✕ 105 m/s at an angle of 37.0°...

plates are then moved 0.48 cm farther apart, the charge on each
plate remains constant but the potential difference between the
plates increases by 100 V.
