Explain how a ballon can be made to stick to a wall electrostatically?

Homework Answers

Answer #1

When a balloon is rubbed against clothes the negative electrons from the clothes get transferred to the balloon making the balloon negatively charged. When the balloon is placed near a wall or ceiling (a neutral object) it stays there and doesn’t fall. This is because the negative charge of the balloon repels some of the electrons in the wall or ceiling away from the surface. This results in an overall positively charged surface causing the negatively charged balloon to be attracted (remember opposite charges attract).

Consider a ‘physical pendulum’ made of a meter stick (length L = 1 m, mass 0.2 kg) with a hole drilled through it at the 5 cm mark. The stick is free to rotate (in a vertical plane) around a nail that goes through the hole and into a wall. Assume no friction between the nail and the hole. The stick’s moment of inertia about the nail is I=0.1 kgm2. (Use g=10 m/s2) If the pendulum is released from rest...
