Question

A total charge Q is broken in two parts Q₁ and Q₂ and they are placed at a distance R from each other. The maximum force of repulsion between them will occur, when ____________.

Options

• `"Q"_2 = "Q"/"R", "Q"_1 = "Q" - "Q"/"R"`

• `"Q"_2 = "Q"/4, "Q"_1 = "Q" - (2"Q")/"R"`

• `"Q"_2 = "Q"/4, "Q"_1 = (3"Q")/4`

• `"Q"_1 = "Q"/2, "Q"_2 = "Q"/2`

Answer 1

A total charge Q is broken in two parts Q₁ and Q₂ and they are placed at a distance R from each other. The maximum force of repulsion between them will occur, when `"Q"_1 = "Q"/2, "Q"_2 = "Q"/2`.

Explanation:

When the magnitudes of two charges are equal, the force between them is greatest.
