Questions & Step-by-Step Solutions
What is the electric potential at a point due to a positive point charge?
Step 1: Understand that electric potential is a measure of the potential energy per unit charge at a point in space due to a charge.
Step 2: Recognize that a positive point charge creates an electric field around it.
Step 3: Know that the electric potential (V) at a distance (r) from a positive point charge (Q) can be calculated using the formula: V = k * Q / r, where k is a constant (approximately 8.99 x 10^9 N m²/C²).
Step 4: Realize that as you move further away from the charge (increasing r), the electric potential (V) decreases.
Step 5: Conclude that the electric potential is positive when measured at any point outside the charge.
