Question
Which of the following are correct about the direction of electric field E at a point P? i. radially outward if the charge is positive ii. radially inward if the charge is negative iii. radially inward if the charge is positive iv. radially outward if the charge is negative
Correct Answer
Option A is the correct answer.
Detailed Explanation
Field lines point AWAY (radially outward) from positive charges and TOWARD (radially inward) negative charges. So statements i and ii are the correct pair; iii and iv are their reverses and are false.
Hint
Field lines point AWAY (radially outward) from positive charges and TOWARD (radially inward) negative charges.
