Question

Two charged spheres are placed as shown above. The size of the sphere represents how much charge it has. Choose the position (indicated by A, B, or C) where there would be zero electric field. A B C Question 2 A charged sphere has a radius of 5.70 cm. The electric field strength at a distance 15.9 cm is 2.30×10^3 N/C. If the sphere's radius is halved (but the total charge stays the same), what would the strength of the electric field at 15.9 cm become? 4.60E+03 N/C 575 N/C 1.15E+03 N/C 2.30E+03 N/C Question 3 Two charged, square plates, separated by a distance of 17.9 cm and each with a side length of 26.8 cm, make up a parallel-plate capacitor. The electric field inside the plates is 2.50×10^3 N/C. If the side length is doubled (but leaving the total charge the same), what would the electric field inside the plates become? 2.50E+03 N/C 1.25E+03 N/C 5.00E+03 N/C 625 N/C Question 4 In the figure above, a neutral and unpolarizable object at position 3 is let go from rest. Describe the object's motion. It accelerates to the left. It moves to the left at constant speed. It accelerates to the right. It remains at the same position. It moves to the right at constant speed.
