Question

if A SOAP BUBBLE IS GIVEN SOME positive charge then its radius :-
1) DECREASES
2) REMAINS SAME
3) INCREASES
4) MAY OR MAIN GREASE OR
DECREASE
​

Answer 1

Hey Friend...

Here is your answer...

Correct option is 3). Increases.

Negative charge will be distributed uniformly on the surface of soap bubble. There will be external repulsive force due to extra charge, hence its radius increase to attain the new equilibrium.

Hope it helps you!

Thank you!

Answer 2

If a soap bubble is given some positive charge then its radius increases.

• Soap bubbles have a positive charge on their surface and if we give some external positive charge to soap bubbles the same charge will repel each other and increases the radius of the bubble.
• Thus if a soap bubble is given some positive charge then its radius increases.
• Hence the correct option is 3.
