In this arrangement. each point charge experiences a force of magnitude F. In three scenarios below, q, Q, and rare to some multiple of their original values. In each case, fill in the missing value on one of the variables that wil result in a force between the point charges that is equal in magnitude to the original F scenario 1 1q scenario 3 13/224 (38)Q (81256) 15 (V4) 3 (56)Explanation / Answer
F = kqQ/r^2
for the first case
F1 = kqQ / (3R)^2
F/F1 = 9
for second case
F2 = kq(2Q)/(r/2)^2 = 8kqQ/r^2
F/F2 = 1/8
for thirs case
F3 = k(3/2q)(3/8Q)/r^2
= 9kqQ /16r^2
F/F3 = 16/9
