Question

Electric potential 'V' at a distance 'r' from a point charge is directly proportional to ............

• A. \( r \)
• B. \( r^2 \)
• C. \( \frac{1}{r} \)
• D. \( \frac{1}{r^2} \)

Hint:

Remember the difference: Electric {Potential} (\(V\)) is proportional to \( \frac{1}{r} \). Electric {Field} (\(E\)) is proportional to \( \frac{1}{r^2} \).

Answer 1

The Correct Option is C

The electric potential (V) created by a point charge (q) at a distance (r) from the charge is given by the formula: \[ V = k \frac{q}{r} \] where k is Coulomb's constant. From this formula, it is clear that the electric potential V is inversely proportional to the distance r, or directly proportional to \( \frac{1}{r} \).
