Question: Two stationary point charges + 3.00nC and -2.00nC are separated by a distance of 50.0cm. An electron is released from rest at a point midway between the two charges and moves along the line connecting the two charges.
Part A: What is the speed of the electron when it is 10.0cm from the + 3.00nC charge?
Please help, completely confused!! Give steps if possible for above question.
