Question

An electric field can be created by a single charge or a distribution of charges. The electric field a distance r from a point charge q' has magnitude {E}=k\frac{|q'|}{r^2}. The electric field points away from positive charges and toward negative charges. A distribution of charges creates an electric field that can be found by taking the vector sum of the fields created by individual point charges. Note that if a charge q is placed in an electric field created by q', q will not significantly affect the electric field if it is small compared to q'. Imagine an isolated positive point charge with a charge Q (many times larger than the charge on a single electron). Part B For the same situation as in Part A, on which of the following quantities does the electric field at the electron's position depend?

Answer 1

PART B
Answers:
the distance between the positive charge and the electron
the charge of the positive charge

The electrostatic force cannot exist unless two charges are present. The electric field, on the other
hand, can be created by only one charge. The value of the electric field depends only on the charge
producing the electric field and the distance from that charge.
