1. (9 points) Find the electric force between two electrons each with a charge of 1.6 x 10-19 C if they are located 0.50 μm apart. (1 μm = 1 x 10-6 m). Is this an attractive or repulsive force? Be sure to show all work and use proper scientific notation and significant figures in your answer.
- (10 points) Find the magnitude of an electric field located 2.00 cm from a source charge of 7.0 nC. (1nC = 1 x 10-9 C).
Will the field lines point toward or away from the source charge? Show your work and include an electric field diagram assuming the source is a point charge.
- (6 points) What is the electric potential difference of an electron moved 15.00 mm in an electric field if the potential energy changes -2.00 J? Show your work. See question 1 for charge of an electron.
