- a total charge of 6.3x10^-8 is distributed uniformly throughout a 2.7 radius sphere. Thee volume charge density is: Answer: 7.6x10^-4c/m^31.6. A uniformly charged insulating rod is bent into the shape of a semicirele of radius R = 5 cm. If the rod has a total charge of Q = 3.10°C, find the magnitude and direction of the electric field at 0, the center of the circle. (Answer: E = 6,84.10ʻV/m)Suppose we have a charge, q1=1 μC. This charge makes an electric field some distance r=73 cm away from it. Now suppose our measurement of q1 is only accurate to within 0.2 μC, and our measurement of r is only accurate to within 1.5 cm. What is the uncertainty in our field calculation due only to the uncertainty in the charge separation r? My answer for this was 694.05 N/C which was wrong

Flag question (i.e. Use the following notation (without the quotes): "/" for division, "*" for multiplication, "+" an "-" as usual. For powers used "^2", while for square root use "sqrt". To indicate that square root applies to the whole expression use brackets - for example, for √AB use sqrt(A*B). For Greek letters such as π, a etc. use pi, alpha. For example to get 1 AVAB use 1/pi* A^2/B*sqrt(AB). Please use the exact variables given in the conditions of the problem: e.gif L is given, then do not use 1.
