Question

The diagram below shows a positive point charge Q. Which of the following describes the magnitude and direction of the electric field at points r and s respectively?
Options
A Same and Away from Q
B Same and towards Q
C different and Away from Q
Correct Answer
D different and towards Q
Correct Answer

Option C is the correct answer.

Detailed Explanation

Without the figure, this is answered on general principle: for a positive charge, the field always points AWAY from Q, and its magnitude falls off as 1/r2, so unless r and s are equidistant from Q the magnitudes differ. Best-supported answer: different and away from Q.

Hint

Without the figure, this is answered on general principle: for a positive charge, the field always points AWAY from Q, and its magnitude falls off as 1/r2, s...
