Question

The magnitudes of the electric potential and if the electrostatic force depend on which factors

Answer 1

A. Mass and distance
B. Distance and amount of charge
C. Mass and amount of charge
D. Density and amount of charge

Answer 2

a, c, d) is it gravity, or electricity?
The SOURCE for everything electrical is electric charge.
... too bad they ignored the electric permitivity or k (absolutely necessary!)

Answer 3

I think it is charge, that is why B needs further consideration.

Answer 4

and Force comes from closeness (proximity), not distance.

Answer 5

\(\vec F = k \frac{Q_1 \ Q_2}{r^2} \hat r\)
\(V = -\frac{k \ Q}{r}\)

Answer 6

@IrishBoay123 's has got it, charge and distance are the variables that determine electrostatic force and electric potential.

See my favorite lecture on the subject -
