Question

1.     Imagine an isolated positive point charge Q (many times larger than the charge on a single proton). There is a charged particle A (whose charge is much smaller than charge Q) at a distance from the point charge Q. On which of the following quantities does the magnitude of the electric field created by charge Q at particle A's position depend? Check ALL that apply.

the type of the charge on the charged particle A

the relative orientation between Q and A (while the distance between Q and A is fixed)

the specific location of the charged particle A (while the distance between Q and A is fixed)

the amount of the charge on the point charge Q

the specific location of the point charge Q (while the distance between Q and A is fixed)

the distance between the point charge Q and the charged particle A

the amount of the charge on the charged particle A

the type of the charge on the charged particle A

the relative orientation between Q and A (while the distance between Q and A is fixed)

the specific location of the charged particle A (while the distance between Q and A is fixed)

the amount of the charge on the point charge Q

the specific location of the point charge Q (while the distance between Q and A is fixed)

the distance between the point charge Q and the charged particle A

the amount of the charge on the charged particle A

Explanation / Answer

E = kQ/r^2

Magnitude will depend only on the distance between Q and A

And amount of charge on Q
