A soap bubble is given a negative charge, then its radius

A

Decreases

B

Increases

C

Remains unchanged

D

Nothing can be predicted as information is insufficient

Text Solution

Verified by Experts

The correct Answer is:
B
For attain more stability every system tends to decrease its potential energy. When we increase charge on soap bubble its radius increases as `U prop 1/r`
