An electron initially at rest is placed in an electric field 2x104 N/C directed west. The distance between the plates is 1 cm. a) What is the acceleration of the electron due to the field?
b) What will be the speed of the electron after it leaves the hole?

Photoelectrons with a maximum speed of 6.50 x 107 m/s are ejected from a surface in the presence of light with a frequency of 6.75 x 1014hz. if the mass of an electron is 9.10 x 10-31 kg, calculate in joules the maximum kinetic energy of a single electron. 3.84 x 10-15 j 1.92 x 10-15 j 5.92 x 10-23 j 3.07 x 10-16 j

How would a small bar magnet be oriented when placed at position x?
