## Homework Statement

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.

## Homework Equations

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!
