What will be the effect on the radius of a soap bubble on giving it a negative charge?

In an uncharged soap bubble, there is equilibrium between the positive and negative charges and it remains stable. Hence, the radius of the bubble will increase when it is given a negative charge.

What happens when negative charge is placed on a soap bubble 1 point a its radius decreases b its radius increases C the bubble collapses D none of these?

The radius of the bubble will expand because the charged particles uniformly distributed on it causes them to repel each other due to the electrostatic force. The phenomenon takes place in both positive and negatively charged bubbles because of the charge on it.

How will the radius of flexible ring change if it is given positive charge?

Initially, the ring has no charge but as soon as we induce positive charges on it, the charges repel each other as like charges repels, so the radius of flexible ring will increase.

When a soap bubble is given a positive charge then its radius 1 A decreases B increases C remains unchanged d nothing can be predicted as information is insufficient?

Whether the bubble is given negative charge or positive charge, the radius will increase in both cases because when positive charge is given to it, again the charges will repel each other and this will expand the bubble and the radius will increase.

When a soap bubble is given a charge?

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.

When soap bubbles have a negative charge?

Therefore, when a negative charge is given to the soap bubble, then its radius will increase. So, the correct answer is “Option A”.

How the excess pressure in a soap bubble changes by doubling the radius?

Here, the surface tension of the soap bubble can be considered to be a constant value. Therefore, the excess pressure inside a soap bubble is inversely proportional to its radius.

Why does the radius of a soap bubble increase with charge?

There will be repulsion and the radius will increase. Same in case of negative charge given to the bubble! 😀 As there is only one type of charge on the whole outer surface of soap bubble, then due to net repulsion between charges the radius of soap bubble will increase till the surface tension can keep up with the electrostatic force of repulsion.

What happens to the surface of a bubble when charged?

Please explain. Charge will be distributed uniformly on the surface of a bubble if the bubble is charged. The bubble will expand because the charged particles uniformly distributed on it cause them to repel each other due to the electrostatic force. This will happen to both positive and negatively charged bubbles because of the charge on it.

How does surface tension affect the surface tension of soap bubbles?

Of course, the increase in restoring force of the soap film (surface tension) will at some point be equal and opposite to the electrostatic force, resulting in a new (larger) equilibrium radius. This will happen to both positive and negatively charged bubbles because of the ionic similarity.

What will increase the radius of the bubble at the point?

∙  Hence the radius of the bubble will Increase. Hence Correct answer is B. Note:There will be a finite increase in radius of the bubble up to the point, when mutual Electrostatic repulsion of negative charges is balanced by the force of Surface tension of bubble and pressure forces from outside and inside.
