When a soap bubble is given a positive charge what happens to its radius?

When a soap bubble is given a positive charge what happens to its radius?

This can occur in both positive and negatively charged bubbles due to their ionic similarity. Therefore we can conclude that when the soap bubble is given a positive charge or negative charge, then the radius of the soap bubble will increase. Hence the correct answer is option B.

What is the radius of soap bubble?

16πr2S.

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 given a negative charge?

Because of the ionic similarities, this can happen to both positive and negatively charged bubbles. Therefore, when a negative charge is given to the soap bubble, then its radius will increase.

Is soap bubble positively charged?

A soap bubble is given a negative charge.

When the radius of soap bubble is increased from 1?

The radius of a soap bubble is increased from 1√π cm to 2√πcm If the surface tension of water is 30 dynes per cm, then the work done will be. 180 ergs.

Does surface tension depend on area?

No, surface tension doesn’t depend on the surface area. The surface tension primarily depends on the forces of attraction between the particles within the giving liquid and also on the gas, solid or liquid in contact with it.

When a conducting soap bubble is negatively charged then?

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

When a system is charged negatively What is the effect on its mass?

Mass of a body decreases slightly when it is negatively charged.

When a negative charge is given to a body its mass?

When a body attains negative charge, it has excess of electrons in it. Electrons has got mass so its mass increases when negatively charged.

What will change the radius of soap bubble?

The radius of a soap bubble is inversely proportional to the surface tension of the soap bubble. If the radius of a soap bubble is increased to the surface tension of the soap bubble will decrease. On the other hand the radius of a soap bubble decreases so the surface tension of the soap bubble will increase.

When the radius of a soap bubble is increased from 1 cm to 2 cm The work done is 720 erg the surface tension of soap solution is?

When the radius of a soap bubble is inreased from 1√π in to 2√πcm, the work done is720 erg. Find the surface tension of the soap solution. A soap bubble of radius 12 cm is blown. Surface tension of soap solution is 30dyne/cm.

What happens to a soap bubble when it is negatively charged?

However, if a soap bubble is negatively charged, then its radius increases. The negative charge will distribute itself evenly over the surface of the bubble, and the repulsion between the negative charges will cause it to expand until the tension can bring it to equilibrium. The electrostatic force will act as the balancing force.

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.

Does Q2 always expand in radius when given a negative charge?

In equation (A), q2 is not affected by positive or negative charge hence , whether it is given a positive or negative charge it always expands in radius. Was this answer helpful?
