Question

Coulomb's law states that the force between two point charges \(Q_1\) and \(Q_2\) is :
• [A.] Along the line joining them.
• [B.] Directly proportional to the product of charges \(Q_1\) and \(Q_2\).
• [C.] Inversely proportional to the distance \(R\) between them.
• [D.] Inversely proportional to the square of distance \(R\) between them. Choose the correct answer from the options given below :

• A. A, B, C Only
• B. A, B, D Only
• C. B, C Only
• D. B, D Only

Hint:

Coulomb’s law: \[ F=\frac{1}{4\pi\epsilon}\frac{Q_1Q_2}{R^2} \] Electrostatic force follows inverse square law.
