W4D1 Continuous Charge Distributions Chapter 16 Electric Field of Distributed Charges The Math for the rod (from class) www.iclicker.com
Activity – The Hard Part! BREAKING UP THE ROD
Let’s review the math a little y=L/2 Total charge = Q Total Length=L m=Q/L switch from dy to Dy dy y O dq=mdy x-axis 
Doing the math From tables of integrals …
What happens when L gets really big compared to L? (Infinite line of charge)
What happens when L is very SMALL compared to r?? (Teeny Tiny.) coulomb’s Law!!
