The electric potential due to a point charge is given by which formula? (2019)
Step 1: Understand that we are talking about electric potential, which is a measure of the potential energy per unit charge.
Step 2: Identify that the electric potential is created by a point charge, which is a charge concentrated at a single point.
Step 3: Recognize that the formula for electric potential (V) involves the charge (Q) and the distance (r) from the charge.
Step 4: Learn that Coulomb's constant (k) is a proportionality factor in the formula.
Step 5: Write down the formula: V = kQ/r, where V is the electric potential, Q is the point charge, r is the distance from the charge, and k is Coulomb's constant.
