What is the electric potential at a distance of 3 m from a charge of 10 μC?
3000 V
9000 V
6000 V
1000 V
V = k * q / r = (9 × 10^9 N m²/C²) * (10 × 10^-6 C) / (3 m) = 30000 V / 3 = 9000 V.

Q: What is the electric potential at a distance of 3 m from a charge of 10 μC?
Solution: V = k * q / r = (9 × 10^9 N m²/C²) * (10 × 10^-6 C) / (3 m) = 30000 V / 3 = 9000 V.
Steps: 6
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) = 10 μC = 10 × 10^-6 C, and r (the distance) = 3 m.
Step 3: Substitute the values into the formula: V = (9 × 10^9 N m²/C²) * (10 × 10^-6 C) / (3 m).
