Physics · Electrostatic Potential
हिन्दीGiven below are two statements: Statement I: The work required to separate two opposite charges \( +q \) and \( -q \) from an initial finite distance to infinity is positive. Statement II: The mutual electrostatic potential energy of two like charges is negative. In the light of the above statements, choose the most appropriate answer from the options given below:
Correct answer · Option 3
Statement I is correct but Statement II is incorrect.
Explanation
For opposite charges, U = -q^2/(4 pi eps0 r) < 0, so work to separate to infinity is W = 0 - U > 0. For like charges, U > 0 (positive), so Statement II is incorrect.
