Question
Which is/are correct about Coulomb's law? i. For similar charges, force is positive ii. For non-identical charges, the force is negative iii. For similar charges, force is negative iv. For non-identical charges, force is positive
Correct Answer
Option A is the correct answer.
Detailed Explanation
By convention, a repulsive force (between like/similar charges) is taken as positive, and an attractive force (between unlike/non-identical charges) is taken as negative. So statements i and ii are correct.
Hint
By convention, a repulsive force (between like/similar charges) is taken as positive, and an attractive force (between unlike/non-identical charges) is taken...
