A proton is traveling horizontally to the right at 5.00×106 m/s .
A) Find the magnitude of the weakest electric field that can bring the proton uniformly to rest over a distance of 3.40 cm.
B) How much time does it take the proton to stop after entering the field?
C) What minimum field magnitude would be needed to stop an electron under the conditions of part A? What is the direction of the field?
A uniform electric field exists in the region between two
oppositely charged plane parallel plates. A proton is
released from rest at the surface of the positively
charged plate and strikes the surface of the opposite
plate, 1.60 cm distant from the first, in a time interval
of 1.50 × 10-6 s.
a. Find the magnitude of the electric field.
b. Find the speed of the proton when it strikes the
negatively charged plate.
Hint: Use both kinematics and electric field equations in solving the
problem
Inside a vacuum tube, an electron is projected between two parallel
Problem 1
plates. The plates are separated by 3 cm and are 10 cm long. Equal but opposite electric
charges are placed on the plates, so that there is a uniform electric field between the plates
and no field outside of the plates. The electron is projected in the center of the positive
plate and its initial velocity is 4.5 x 10 m/s straight towards the center of the negative plate.
Find the magnitude of the electric field such that the electron just barely misses touching the
negative plate before it turns around goes directly back out of the hole.
