When a soap bubble is charged?
- A Its radius increases
- B Its radius decreases
- C The radius remains the same
- D Its radius may increase or decrease
Answer & Solution
Correct Answer
(A) Its radius increases
Step-by-step Solution
Detailed explanation
When a soap bubble is charged, then the bubble expands because the charged particles uniformly distributed on it causes them to repel each other due to the electrostatic force. Hence, radius of soap bubble increases.
