Force f acts between a pair of charges, q1 and q2, separated by a distance d. for each of the statements, use the drop-down menus to express the new force in terms of f.
q1 is halved, q2 is doubled, but the distance between the charges remains d.
f
q1 and q2 are unchanged. the distance between the charges is doubled to 2d.
f/4
q1 is doubled and q2 is tripled. the distance between the charges remains d.
