F = k q1q2/r^2
See what happens, for example a) make q1, q1/2

b.The charge on both spheres is doubled
c.The distance between the spheres is increased by a factor of three
d.The distance between the sphere is decreased to one-fourth
e.The charge of each sphere is doubled and the distance between them is doubled
