Answer:
A. the distance between the positive charge and electron
B. The charge on electron
D. The magnitude of charge on positive charge
Explanation:
From Coulumb's law we know that the electrostatic force between two charges is directly proportional to product of the magnitude of their charges, and inversely proportional to the square of distance between them.
Mathematically:
[tex]F=\frac{kq_{1}q_{2} }{r^{2} }[/tex]
Thus following will apply:
A. the distance between the positive charge and electron
B. The charge on electron
D. The magnitude of charge on positive charge
