What is the electric potential at a point 0.4 m away from a charge of +5 µC?
Step 1: Identify the formula for electric potential (V) due to a point charge, which is V = k * q / r.
Step 2: Determine the values needed for the formula: k (Coulomb's constant) = 9 × 10^9 N m²/C², q (the charge) = +5 µC = 5 × 10^-6 C, and r (the distance from the charge) = 0.4 m.
Step 3: Substitute the values into the formula: V = (9 × 10^9) * (5 × 10^-6) / 0.4.
