Question

Can you help me with this?
An electron (mass=9.11X10-31kg) is accelerated in theuniform field E (E=1.85X104 N/C) between two parallelcharged plates. The separation of the plates is 1.00cm. The electron is accelerated from rest near the negativeplate and passes through a tiny hole in the positive plate.
A) with what speed does it leave the hole? (in m/s)
B) Explain why the gravitational force can be ignored.
mg/qE is on the order of 10-15N, mg/qE is on the orderof 10-7N, or mg/qE is on the order of 107N

Explanation / Answer

Mass m = 9.11 * 10 ^ -31 kg

Electric field E = 1.85 * 10 ^ 4 N / C

Separation d = 1 cm = 0.01 m

Initial speed u = 0 m / s

Accleration a = E q / m
