Physics 29/01/14

Things we covered today

Drawing of charges:
DO NOT draw any charges on a neutral object.
3. If an object is charged, draw and distribute the excess charges uniformly on the object. The charges should be well-distributed uniformly on the object as like charges repel.
1. When charging by induction
(Single Sphere)
(2 Spheres)

Common Misunderstandings:      Correction:
1. Neutrally-charged objects        No such thing           
2. Positive charges move             Only electrons can flow/move
