Consider the following figure. (If you need to use  or –, enter INFINITY or –INFINITY, respectively.) (a) Find the total electric field in N/C at  x = 5.00 cm  in part (b) of the figure above given that  q = 5.00 nC.   N/C (b) Find the total electric field in N/C at  x = 11.50 cm  in part (b) of the figure above. (Include the sign of the value in your answer.)   N/C (c) If the charges are allowed to move and eventually be brought to rest by friction, what will the final charge configuration be? (That is, will there be a single charge, double charge, etc., and what will its value(s) be? Use the following as necessary: q.)

Suppose we have a charge, q1=3 μC. This charge makes an electric field some distance r=69 cm away from it. Now suppose our measurement of q1 is only accurate to within 0.1 μC, and our measurement of r is only accurate to within 1 cm. a)If we were to calculate the electric field made by that charge at the indicated distance, what would be the uncertainty in our calculation due only to the uncertainty in the size of q1? b)What is the uncertainty in our field calculation due only to the uncertainty in the charge separation r?   c)What is the total uncertainty in our electric field calculation due to the uncertainty in the size of q1 and the uncertainty in the charge separation r?
