Size of a soap bubble when charged

Share with:


What will happen to the size of the soap bubble if the bubble is given charges ?


Asked VARSHA UDAYAKUMAR

Answer: When a soap bubble is charged, its size increases.

Under normal condictions, a soap bubble is in equilibrium un der two opposing forces – the force of surface tension which tries to compress it and the force due to excess pressure which tries to expand it.

When charged, the force of repulsion among the like charges will try to expand the soap bubble further resulting in an increase in size of the bubble.
