Question

Two plastic cups are placed 25 cm apart. What factors determine the strength of the electric field between these two cups? Select all that apply.

A) the charge on Cup A
B) the charge on Cup B
C) the distance between the cups
D) whether the cups are insulators or conductors

Answer 1

A, B, and C all apply.

Step-by-step explanation:

The strength of the electric field between two charged objects is directly proportional to the magnitude of the charges (A and B) and inversely proportional to the distance between them (C). The type of material the cups are made of (insulators or conductors) does not affect the strength of the electric field.
