Equilibrium is established when the electric force between the
balls = weight of upper ball .. this force is constant at any
spacing.
F = k.q1.q2 / d² .. .. For constant F .. q1.q2 ∝ d² .. .. d ∝
√(q1.q2)
When q1 halved .. (q1.q2) decrease by a factor of 2 .. and d by a
factor √1/2 = 1/√2
Ans .. ►(d) d/√2
E is vector
V is scalar
C. is true

55. 11 You have two small, 2.0 g balls that have been given equal but opposite charges, but you don't know the magnitude of the charge. To find out, you place the balis distance d apart on a slippery horizontal surface, release them,and use a motion detector to measure the initial acceleration of one of the balls toward the other. After repeating this for several different separation distances, your data are as follows: Acceleration (m/s2) Distance (cm 2.0 3.0 4.0...

Just "B" please in detail.
Imagine that we suspend two small plastic spheres with mass m using insulating threads of length L from a common point. If the spheres are uncharged, they will hang so they touch; but when they are both given the same charge q, they repel each other and hang a distance d apart, as shown below. Assume that d is pretty small compared to L but large compared to the diameter of the balls. (a) Explain,...
