Find the electric field due to a half circle of radius R and total charge Q. (a) First estimate by dividing the charge into five equal parts. (b) Repeat for 9 equal parts, (c) Using integral calculus solve exactly.
E = kQ/r^2
The Attempt at a Solution
Cant remember too much from doing these before...for a start I guess...
a) break into 5 parts....
Q = Q/5
Just need some help getting going!
Thanks in advance!
