If two ping-pong balls are suspended near each other and a fast stream of air is produced in the space between the balls, then the ball

Three small equally charged identical conducting balls are suspended from identical insulating threads secured at one point. Length (L) of the threads is large compared to the equilibrium separation (a) between any two balls. (a) One of the balls is suddenly discharged. Find the separation between the charged balls when equilibrium is restored. Assume that the threads do not interfere and balls do not collide. (b) If two of the balls are suddenly discharged, how will the balls behave after this? Find the separation between the balls when equilibrium is restored. The threads do not interfere

Define a ping-pong ball in an air jet.

A ping-pong ball remains dancing at a height in a vertical stream of water.Explain how?

When air is blown in between the two balls, will they attract or repel?

The distance between two equal balls having unlike charges is 2cm. The radii of the balls are much less than the distance between them. The balls attract each other with a force of 36xx10^(-5) N. After the ball have been connected by a wire and latter has been removed, the balls repel each other with a force of 20. 25xx10^(-5)N. Determine the original charges on the balls

Two similar conducting balls having charges + q and - q are placed at a separation d from each other in air. The radius of each ball is r and the separation between their centres is d (d gt gt r ). Calculate the capacitance of the two ball system
