The diagram shows electric field lines around two isolated point charges P and Q. At X, the field strength is zero.
Which of the following statements is true?
A
Q is a smaller charge than P because X is closer to P than Q
B
Field strength is always proportional to the distance from X
C
The potential at Q is less than the potential at P
D
The field lines show that both charges are positive
Answer
The field lines show that both charges are positive
Explanation
Solution
Both charges are positive.
