Two uncharged, conducting spheres are separated by a distance d. When charge -Q is moved from sphere A to sphere B, the Coulomb force between them has magnitude F0. (a) Is the Coulomb force attractive or repulsive? (b) If an additional charge -Q is moved from A to B, what is the ratio of the new Coulomb force to the original Coulomb force, Fnew /F0? (c) If sphere B is neutralized so it has no net charge, what is the ratio of the new to the original Coulomb force, Fnew /F0?

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. m

Two charges are located in the xy plane: charge q₁ = -3.35 nC is located at (x = 0.00 m, y = 1.000 m); charge q2 = 3.40 nC is located at (x = 1.40 m, y = 0.450 m.) Calculate the x and y components, Ex and Ey, respectively, of the net electric field È at the origin. The value of the Coulomb force constant is 1/(4€) = 8.99 × 10⁹ Nm²/C². Ex = N/C Ey = = N/C

You have two identical conducting spheres, each of mass m, the first one being charged twice as the second one, and the spheres are charged with oppositely charges. They are separated by a distance 'd. What should be the charge on the spheres so the force of attraction between the spheres will be equal to the weight of each sphere ? Take Coulomb constant as simply 'k'. q1 = (d/2)(mg/k), q2 = (d/2/2)(mg/2k) 91 = (d/2)(mg/2k), q2 = (d/ 2)(mg/k) 91 = (d//2)(mg/k), q2 = (d/2/2)(mg/k) %3D O 41 = (2d//2)(m²g/k), q2 = (d/2/2)(mg/2k)

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?

A particle of mass 5.4×10^−6 g and a charge of −2 nC starts out traveling horizontallyat 500 m/s straight between two oppositely charged plates separated by 3 cm. The plateshave surface charge densities of 9 µC/m^2Determine the following:a) How long till it impacts either plate?b) How far will it travel horizontally until it impacts one of the plates?
