What is the electric potential at a point 1 m away from a charge of +1 µC?
Correct Answer: 8.99 kV
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) = 8.99 x 10^9 N m²/C², q (the charge) = +1 µC = 1 x 10^-6 C, and r (the distance from the charge) = 1 m.
Step 3: Substitute the values into the formula: V = (8.99 x 10^9 N m²/C²) * (1 x 10^-6 C) / (1 m).
Step 4: Calculate the result: V = 8.99 x 10^3 V, which is equal to 8.99 kV.
