What happens to two charged objects as the distance between them increases?

What happens to two charged objects as the distance between them increases?

In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects. Electrostatic force and distance are inversely related.

When a body is charged Its mass is?

Charging of any body is the process of increasing or decreasing the number of electrons. The mass of the electrons is almost negligible. Thus, the mass of the body remains unaffected while charging or discharging the body.

What is the excess pressure inside a soap bubble?

The excess pressure across a soap bubble of radius r is p=4σ/r, where σ is the surface tension of soap solution.

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.

Why does the size of a soap bubble increase at the time of charging?

There is equilibrium inside positive and negative charges of soap bubble. To achieve this equilibrium, charges try to repel each other. Thus the surface area of bubble increases. Due to increase in surface area, the bubble increases in size.

When a soap bubble is positively charged its radius?

Answer. if a soap bubble is given some positive charge then its radius increases. 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.

When a charged soap bubble is extended what will be the change in its potential?

When external charge is put on the surface of the bubble, it gets distributed uniformly over the entire surface of the bubble, which increases the potential at the surface (with respect to some origin, say the center of the bubble).
