- A small sphere of charge q = +65 μC and mass m = 5.3 g is attached to a light string and placed in a uniform electric field E that makes an angle 8 = 38° with the horizontal. The opposite end of the string attached to a wall and the sphere is in static equilibrium when the string is horizontal as in the figure shown below. + (a) Construct a free body diagram for the sphere. (Submit a file with maximum size of 1 MB.) Choose File No file chosen (b) Find the magnitude of the electric field. N/C (c) Find the tension in the string. (Enter the magnitude of the tension in the string.) N2bPart a) A +6 nC charge is located 3.6 meters to the right of a +5 nC charge. Determine the magnitude of the electric field at the midpoint of the two charges. Express your answer as a positive number in N/C. Part b) A 10 nC charge generates an electric field within an isolated chamber. At a point a distance d meters away from the charge, the electric field is measured to be 4 N/C. Determine d in meters. Use k=9 x109 for the electric constant.
- Questions D,E, and magnitude of final velocity please :)I need help with this problem. I am really struggling figuring it out. Any help is greatly appreciated! Consider a region in which a uniform electric field of 25 N/C is directed to the east. A negative point charge is released from rest within this field. The charge on this particle is -3.7 nC and its mass is 6.1 x 10-10 kg. How far and in what direction will the object travel in 0.25 s?
