a) What is the potential difference between two points situated 8.0 cm and 34.0 cm from a +5.0 nC point charge?

b) Sketch the equipotential lines near the +5.0 nC point charge. Indicate the direction of increasing potential.

c) Use q to represent a test charge. Place the test charge q in your drawing from above. Be sure to indicate the direction the test charge will move in the electric field created by the +5.0 nC point charge.
