Announcement Beginning next Tuesday, you should pick a seat and sit in it every time. We will take attendance by checking which seats are occupied. – p. Today • Continuous charge distributions. • Charge density • Integrating to get the electric field • Field lines – p. Tricks of the Trade – p. Tricks of the Trade • Make approximations – p. Tricks of the Trade • Make approximations • Use symmetry – p. Tricks of the Trade • Make approximations • Use symmetry • Solve problems algebraically – p. From the Equation Sheet F 2 on 1 = 1 4 π q 1 q 2 ( r 1 − r 2 ) | r 1 − r 2 | 3 F = q E d E (at r ) = 1 4 π dQ ( r − r ) | r − r | 3 – p. Limiting Case I Close to a long wire: x a ⇒ √ x 2 + a 2 ≈ a + a- a x E = 1 2 π λ x a √ x 2 + a 2 ˆ...
