We looked at electric field this time. It follows E=F/q. Then we substute F=kq1q2/r^2/q to get E=kq/R^2.
In real situation, charges are in three dimension. We graphed it.
We also did it in vpython.
We then calculated some electric field due to two point charges.
We calculated the electric field.
We did it in an excel spreadsheet to calculate the electric field due to a charged rod.
