When the distance between the centers of two charged spheres is increased by 10%, how much does the magnitude of the electric force on one of the spheres change?

A. If the two spheres both have the same sign charge, the force decrease about 20\$ , but if they have opposite charge it increases by about 20%
B. The force must decrease by about 5%
C. The force must increase by 10%
D. The force must increase by about 20%
E. If the two spheres both have the same sign charge, the force increases about 20%, but if they have the opposite charge, it decreases by about 20%
F. You have to know the details on the charge on the spheres to answer
G. The force must decrease by about 20%
H The force must decrease by 10%
I. The force must increase by about 5%.
