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?

1. Two thin conducting plates, each 30 cm on a side, are situated parallel to one another and 5 mm apart. If 1.3.10¹2 electrons are moved from one plate to the other, what is the electric field between the plates? (a) In your notebook, draw the two conducting plates and draw the electric field lines between the plates. How is the electric field directed? v (b) Calculate the surface charge density of the plates. C/m 0= (c) What is the electric field between the plates? E= N/C 2

A test charge of +3 µC is at a point P where an external electric field is directed to the right and has a magnitude of 4.0x106 N/C. The test charge is replaced with another test charge of -3 µC. The external electric field at P from the source chare will ________. (increase, decrease, remain the same.) How do you know this?
