Electrostatics | MCQs

Explanation

An electroscope detects the presence and type of electric charge on a body.

It shows whether the charge is positive or negative by the movement of its leaves.

Explanation

According to Coulomb's Law, the force between two charges decreases as the square of the distance between them increases.

Formula: F ∝ 1/r², where r is the distance between the charges.

Explanation

Explanation

When a soap bubble is charged, the repulsive forces between like charges on the surface of the bubble cause the bubble to contract, decreasing its size.

Explanation

Electrostatics is the branch of physics that deals with the study of stationary electric charges, also known as static electricity.

It involves the study of electric charges at rest, their properties, and the forces that act upon them.

Explanation

The dipole moment of H₂O (water) is approximately 1.83 Debye.

This is due to the bent shape and the difference in electronegativity between hydrogen and oxygen.

Explanation

The molecule that is polar and has a dipole moment of 5.33 x 10^-30 Cm is SO2 (sulfur dioxide).

Explanation

If a positive charge is placed between two negative charges, the system will be unstable due to the repulsive forces between like charges.
