Electrostatics

a. Draw the electric field lines around a positive charge.

b. Calculate the electric force that exists between two objects that are 0.500 m apart and carry charges of 0.00450 C and 0.00240 C. Is this force attractive or repulsive?

c. How does the size of the electric force between two charged objects change if the amount of charge on one of the objects is doubled?

d. How does the size of the electric force between two charged objects change if the charges are moved farther apart?

e. The image below shows a metal sphere on a stand. Based on the charges shown, describe the overall charge on the sphere.

f. On the model below, draw how the negative charges in the same sphere are redistributed when a negatively charged rod is brought near it, as shown.
