1.A charge Q acts on a test charge to make an electric field, E. The strength of the field is measured at 8 N/C at 40 cm away. What would the field strength be 80 cm away with a

charge of =1/2 Q? Explain.

2.You have a positive test charge brought near a negatively charged ball. Describe what is happening if you move the test charge even closer. Be sure to use the terms Potential Energy, Potential Difference, Force, Work, and Electric Field.

3.Explain what lightning is.

4.How many electrons pass through a light bulb every second if it is connected to a 3.00-volt circuit with a 12.0 o resistance? (e = 1.602 10^-19 C)
