What is the electric potential at a point 1 m away from a +1 C charge?
Step 1: Identify the formula for electric potential (V), which is V = k * q / r.
Step 2: Understand the variables in the formula: k is the electrostatic constant (approximately 8.99 x 10^9 N m²/C²), q is the charge (in this case, +1 C), and r is 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 C) / (1 m).
Step 4: Calculate the result: V = 8.99 x 10^9 N m²/C² * 1 C / 1 m = 8.99 V.
Step 5: Conclude that the electric potential at a point 1 m away from a +1 C charge is 8.99 V.
