A. draw the electric field lines around a negative charge.
b. calculate the electric force that exists between two objects that are 0.900 m apart and carry charges of 0.00150 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 tripled?
d. how does the size of the electric force between two charged objects change if the charges are moved closer together?
e. the image below (first image) shows a metal sphere on a stand. based on the charges shown, describe the overall charge on the sphere.
f. on the model below (second image) draw how the negative charges in the same sphere are redistributed when a positively charged rod is brought near it as shown.
