When a soap bubble is given a positive charge, then its radius:

A

Decrease

B

Increase

C

Remains unchanged

D

Nothing can be predicted as information is insufficient

Text Solution

Verified by Experts

The correct Answer is:
B
Increases
Explanantion : The positive charge is uniformely distributed on the soap bubble it cause repulsive force between charge particles distributed on the bubble due to electristatic force between them , Hence , its radius increases .
