Chapter 4: Q16E (page 778)
Two stationary point charges +3.00 nC and +2.00 nC are separated by a distance of 50.0 cm. An electron is released from rest at a point midway between the two charges and moves along the line connecting the two charges. What is the speed of the electron when it is 10.0 cm from the +3.00 nC charge?
Short Answer
The speed of an electron when it is 10 cm away from q1 is 6.89 x 106 m/s.
