Questions & Step-by-Step Solutions
If the electric potential at a point is 200 V and a charge of -1 C is placed at that point, what is the potential energy?
Step 1: Identify the electric potential (V) at the point, which is given as 200 volts.
Step 2: Identify the charge (q) placed at that point, which is given as -1 coulomb.
Step 3: Use the formula for potential energy (U), which is U = q * V.
Step 4: Substitute the values into the formula: U = -1 C * 200 V.
Step 5: Calculate the potential energy: U = -200 joules.
Electric Potential and Potential Energy – The relationship between electric potential (V) and potential energy (U) is given by the formula U = q * V, where q is the charge and V is the electric potential.
