So for 2. I should use Pythagorean - Sqrt(.02^2+.02^2)?
Ok for vector addition, tip to tail for E.
I believe SW would be right.
But what do you mean about the charge in lower left? Am I not supposed to use E times Q the constant at 1.6*10^-19? Or am I wrong about Q?
Homework Statement
A square has a charge at each corner. The square is 2cm x 2cm. In the upper left corner there is 1μc, in the upper right corner there is 2μc, the lower right corner there is 3μc, and the lower left corner there is 4μc.

I was wrong in that angle. I found the correct angle by assuming no friction, solving the y force for Fn and substituting it in the x force equation. This gave me theta.
Then, after figuring out the x y-axis could be rotated to go with the Fn on the car, solved like any other incline plane...
Homework Statement
A banked curve has been designed so that it is safest for a vehicle going 70 mph. The topography of the land restricts the radius of the road to 300m. Assume mu(static friction) is 0.80 and mu(kinetic friction) is 0.60.
