If opposite charges attract, why then does a balloon stick to a wall that is neutrally charged?
Homework Answers
When a charged balloon is brought near a wall it still sticks to the wall even though the wall is neutrally charged.
It is to be noted here that neutral charge does not mean the absence of charges but equal amount of positive and negative charges.
When the balloon which is usually negatively charged is brought near the wall , the negative charges gets pushed away and the positive charges gets pulled towards the point of contact hence creating a electric dipole in the wall.
Since the positive-negative charges are closer than the negative- negative charges, the attraction force is more and hence the balloon is attracted to the neutral wall.

The reason a charged balloon will stick to a wall is that A) the charge is slightly sticky and acts like glue. B) the rubber of the balloon simply sticks to walls. C) none of the other answers. D) induced opposite charges in the wall are closer than other wall charges. E) electrons transfer back and forth between the wall and the balloon. Two charges are separated by a distance d.

When a charged balloon sticks to a wall, the downward gravitational force is balanced by an upward static friction force. The normal force is provided by the electrical attraction between the charged balloon and the equal but oppositely charged polarization induced in the wall's molecules. If the mass of a balloon is 2.1 g, its coefficient of static friction with the wall is 0.70, and the average distance between the opposite charges is 0.80 mm, what minimum amount of charge...

A uniform meter stick of mass 1.5kg is attached to the wall by a frictionless hinge at one end. On the opposite end it is supported by a vertical massless string such that the stick makes an angle of 40 degrees with the horizontal. Find the tension in the string and the magnitude and direction of the force exerted on the stick by the hinge.
