Suppose a 11 cm diameter conducting sphere, surrounded by air, has 1.9 C of excess charge on it. Calculate the electric field strength near the surface of the sphere, in newtons per coulomb. E= What is unreasonable about this result? Multiple Choice a. There is nothing unreasonable about the result. b. The charge is too large for such a small sphere. None of these. C. d. The charge is too small for such a large sphere. e. An electric field couldn't be near a conducting sphere. Which assumptions are responsible for the unreasonable results? Multiple Choice a. The diameter of the sphere is too large. b. The excess charge on the sphere's surface is too great. C. None of these. d. The excess charge on the sphere's surface is too small. e. The excess charge and the diameter of the sphere are too large
QUESTION 9 An excess positive charge Q is uniformly distributed throughout the volume of an insulating solid sphere of radius R = 4.0cm. The magnitude of the E-field at point P, 8.Ocm from the center of the sphere is given to be 4.5x107N/C. What is the value (in units of uC = 10-°C) of charge Q? (Example: if your answer is Q = 4.2x10-°C, enter your amswer as 4.2 in the answer box).
CONFIGURATION 4 Now we want to look at a charge distribution. You have a total charge of +6.00 nC spread along a line (with a uniform charge density). This charge is spread over 0.5 m in length. Calculate he electric field at a position P, which is 1.5 m away from the closest end of the line of charge (see the image below). Total Q = + 6.00 nC Pt.
