Electrical potential V and electric flux φ are:

The correct answer is Option (4) → V is scalar, \( \phi \) is scalar

The electric potential is the work done per unit charge, \( V = W/q \). Work and charge are scalars, so V is a scalar and potentials of several charges simply add algebraically.

The electric flux is the dot product of the field and the area vector, \( \phi = \vec{E}\cdot\vec{A} \). A dot product is a scalar, so \( \phi \) has only a magnitude and a sign.
