Fig. 1

Draw the field lines around the positively charged ball.

1.2. A second, identical ball is suspended close to the first one. The second ball is also given a positive charge.

Marion says that both balls will hang straight downward, due to the effect of gravity.

State whether Marion is correct, and explain your answer.

1.3. Sketch the arrangement of the two balls hanging next to each other.

Add field lines to your diagram, in support of your answer to part (b).
