## What happens when a soap bubble is given an electric charge?

The bubble collapses. … When the charge is placed on the soap bubble, every part of the surface of the soap bubble has the same charge. So every part of the surface of the soap bubble will repel every other part of the surface which will increase the size (and hence radii) of the soap bubble.

## What is the cause of excess pressure inside a soap bubble?

Answer: Due to surface tension, the molecules on the surface film experience the net force in the inward direction normal to the surface. Therefore, there is more pressure inside than outside.

## When a soap bubble is given a positive charge then its radius A decreases B increases C remains unchanged d nothing can be predicted as information is insufficient?

Nothing can be predicted as information is insufficient.

## What happens when some charge is placed on a soap bubble 1 point a bubble collapses b bubble expands C bubble shrinks little d no change?

The correct answer is its radius increases. What happens when some charge is placed on a soap bubble its radius increases.

## When a soap bubble is charged its radius increases Why?

When the force of repulsion between the charges and the tension force gets balanced, the stretching of the bubble stops due to the equilibrium attained between the forces. Therefore, the size of the soap bubble increases when it is charged due to the repulsion between the charges on the surface of the soap bubble.

## What is excess pressure?

The Reservoir-wave hypothesis states that it is convenient to separate the arterial pressure into a reservoir pressure, that accounts for the energy stored by the elastic walls of the arterial system during systole and released during diastole, and an excess pressure, defined as the difference between the measured …

## When a conducting soap bubble is negatively charged?

Answer: The bubble will expand because the charged particles uniformly distributed on it cause them to repel each other due to the electrostatic force.
