Question
An electron of mass me = 9.1 × 10−31 kg is accelerated in the uniform electric field E between
two parallel charged plates, There is no electric field outside of the plates. The electric field has a
magnitude E = 2.0 × 103 N/C and electron charge e = −1.6 × 10−19 C. The separation of the
plates is 1.5 cm and the electron is accelerated from rest near the negative plate and passes
through a tiny hole in the positive plate. Assume the hole is so small that it does not affect the
uniform field between the plates.
What is its acceleration and with what speed does it leave the hole

- What is the escape speed for an electron initially at rest on the surface of a sphere with a radius of 1.20 cm and a uniformly distributed charge of 1.70 × 10-15 C? That is, what initial speed must the electron have in order to reach an infinite distance from the sphere and have zero kinetic energy when it gets there? The charge of an electron is 1.602 × 10-1⁹ C and its mass is 9.109 × 10-31 kg. Number i Unitsarrow_forwardA sphere of uniform charge density rho=10^−6 C/m 3 has a small hole drilled along its diameter, forming a tunnel from one end of the sphere to the other. An electron is released at the opening of the tunnel and begins to move, speeding up towards the center of sphere. After it passes the center of the sphere, it begins to slow down until it reaches the other end of the tunnel and stops. The electron then moves back up to the first opening and start the cycle again. It repeats this cycle many times. Find the frequency of this cyclic motion.arrow_forwardAn electron is fired at 236,348m/s into a uniform electric field generated by two plates as shown. Determine the maximum magnitude of the electric field if the particle is to exit without hitting either of the plates. The electron enters the region at the midpoint directly between the plates. The length of the plates is 0.41m and the distance between the plates is 0.18m. (Your answer will be the positive magnitude of E in units of N/C, given to 3 decimal places of precision) earrow_forward
