- Two metal spheres of identical mass m = 4.60 g are suspended by light strings 0.500 m in length. The left-hand sphere carries a charge of 0.765 µC, and the right-hand sphere carries a charge of 1.47 μC. What is the equilibrium separation between the centers of the two spheres? 0.6078 x Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four- digit accuracy to minimize roundoff error. mI need help with this question. Thank you!Two identical metallic blocks resting on a frictionless horizontal surface are connected by a light metallic spring having the spring constant 160N/m and an un- stretched length of 0.32m as shown. A total charge of Q is slowly placed on the system, causing the spring to stretch to an equilibrium length of 0.43m as shown. Determine the value of Q, assuming that all the charge resides on the blocks and modelling the blocks as point charges. State your answer in mC to nearest 0.01 mC. Take electric constant ke to be 8.99x10° Nm2/c² Hwwwww (a) (b)

The area has a uniform electric field E = 12.9 N/C, pointing to the right. The mass of the ball is m = 9 kg and the charge is q = +2.6 C. When the ball reaches point B, it travels horizontally there after. The height from A to B is h = 37 m and the horizontal distance between A and B is d = 30 m.

When balls A and B are brought close together (far away from C), the two repel. When A and C are brought close together (far away from B), the two attract. When B and C are brought close together (far away from A), the two attract. Find four solutions for how A, B, and C could be charged (+, - or neutral) relative to one another.
- Two infinite non-conductive parallel plates are separated by a distance of 10.0 cm and have charge distributions of +1.00 µC / m2 and -1.00 µC / m2.

What is the force on an electron located outside the two plates but close to the surface of one of them?We wish to calculate the value of eo. Two small metal conducting balls of mass m, each with charge q, are attached to massless strings of length L and suspended from the ceiling. Since the balls are both positively charged, they repel each other, and so at the ceiling the strings make an angle 0 with each other. In terms of m, q, L, 0, and g, what is eo?Two spherical, hollow conductors are concentrically nested as shown in the cross-sectional diagram below and electrically isolated from each other. A net charge of -3 nC is divided between the conductors, with a total of -12 nC on the inner conductor and +9 nC on the outer one. The charges are, of course, free to move between the surfaces within each shell but cannot move from one shell to the other. The inner conductor has an inner radius of a=2 cm, outer radius of b=3 cm. The outer conductor has an inner radius of c=6 cm, an outer radius of d=8 cm. a (a) In equilibrium, all of the excess charge is found on the surfaces. Why is there no charge between a and b, nor between c and d? (b) Determine the net charge on each surface (ie how much charge is there at r = a, at r = b, at r = c and at r= = d). (c) Is the charge on the outer surface equal to the net charge on the outer container, the net charge of the system, or some other amount? Explain briefly. (d) Find the surface charge…
