Q
Q: A charge of -2 μC is placed in an electric field of 1000 N/C. What is the potential energy of the charge? (2000)
Solution:
Potential energy U = q * V = -2 × 10^-6 C * 1000 N/C = -0.002 J.
Steps: 5
Show Steps
Step 1: Identify the charge value. The charge is -2 microcoulombs (μC). Convert this to coulombs: -2 μC = -2 × 10^-6 C.
Step 2: Identify the electric field strength. The electric field strength is given as 1000 N/C.
Step 3: Use the formula for potential energy (U) in an electric field: U = q * V, where q is the charge and V is the electric field strength.
Step 4: Substitute the values into the formula: U = (-2 × 10^-6 C) * (1000 N/C).
Step 5: Calculate the potential energy: U = -2 × 10^-6 * 1000 = -0.002 J.
