Positively charging a neutral body – Rankers Physics

Properties of Charges: Practice Problem & Solution

A neutral body is charged positively by rubbing it, its weight
Increases slightly
Decreases slightly
Remains constant
May increase or decrease

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Properties of Charges. Understanding the underlying formula is key to arriving at the correct answer below:

When a neutral body is charged positively, it loses electrons. Since electrons have a finite mass \((m_e \approx 9.1 \times 10^{-31}\text{ kg})\), the loss of electrons results in a slight decrease in its mass and weight.
