Question: What is the electric potential energy of a charge of 1 μC placed in an electric potential of 200 V?

Options:

Correct Answer: 0.2 mJ

Solution:

Electric potential energy U = q * V = 1 × 10^-6 C * 200 V = 0.2 mJ.

What is the electric potential energy of a charge of 1 μC placed in an electric potential of 200 V?

What is the electric potential energy of a charge of 1 μC placed in an electric potential of 200 V?

Step 1: Identify the charge value. Here, the charge (q) is given as 1 μC (microcoulomb). Convert this to coulombs: 1 μC = 1 × 10^-6 C.
Step 2: Identify the electric potential value. The electric potential (V) is given as 200 V.
Step 3: Use the formula for electric potential energy (U). The formula is U = q * V.
Step 4: Substitute the values into the formula. U = (1 × 10^-6 C) * (200 V).
Step 5: Calculate the result. U = 1 × 10^-6 * 200 = 0.0002 joules.
Step 6: Convert joules to millijoules. Since 1 joule = 1000 millijoules, U = 0.0002 joules = 0.2 mJ.
