प्रश्न

Two charges of magnitudes −2Q and +Q are located at points (a, 0) and (4a, 0) respectively. What is the electric flux due to these charges through a sphere of radius ‘3a’ with its centre at the origin?

उत्तर

Gauss’ theorem states that the electric flux through a closed surface enclosing a charge is equal to (1/ε0) times the magnitude of the charge enclosed.

The sphere encloses a charge of -2Q thus, `phi 2Q/epsilon_0`
