Problem
Two charges A and B are held at a fixed distance apart. A material M is placed between the charges, where M is either a block of aluminum or a block of rubber. M does not touch the charges. What happens to the magnitude of the electromagnetic force on charge A as a result of the presence of the material?
A. Decreases substantially for both materials.
B. Increases substantially for both materials.
C. Remains approximately the same for both materials.
D. Increases for one material, decreases for the other.
E. Increases for one material, remains same for the other.
F. Decreases for one material, remains same for the other.
