Question

I really need help with this problem. Can you draw correctly both graphics with values for X and Y so I can draw it too....?

The radious is...

Problem 21.93 < 2of2 Constants Periodic Table ▼ Part A A thin ring-shaped object of radius a contains a total charge Q uniformly distributed over its length. The electric field at a point on its axis a distance z from its center is Take the derivative to find zmax where on the z axis (z > 0) E z is a maximum. Assume Q-6.00μ C and a = 100 cm -max = 7.07 cm (2+a2)2 Previous Answers Correct Part B Make a graph of the electric field for z 0 to z-+12.0 cm. +add graphadd pointsdelete graph i graph into reset? help 3.00 2.00

Answer 1

Electric field due to ring - shaped do fact E = 1/4 pi epsilon_0 Q_x/(x^2 + a^2)^3/2 (Be careful with units) we are taking distance here in meter) 1/4 pi epsilon_0 = 9.0 times 10^9 N - m^2/c^2 Q = 6.00 mu c = 6 times 10^- 6 c a = 10 cm = 0.1 m x = 0 - 12 m = 0 - 0.12 m E = 9 times 10^9 N - M^2/C^2 times 6 times 10^- 6 C x/(x^2 + a^2)^3/2 E = 54 times 10^3 x/(x^2 + a^2)^3/2 N/C x = 0 Rightarrow E = 0 x = 0.01 m Rightarrow E_0.01 54 times 10^3 x0.01/(0.01^2 + 0.1^2)^3/2

i used two sheets in MS-exel one for electric field due to ring and one for point charge, made 2 graphs and and merged them togather by copy -pasting one graph on other.
