- 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. mTwo negative charges, each with a charge of -7.7 nC, are at fixed locations as shown below. A proton is launched from the midpoint of the line joining the charges in a direction perpendicular to the line joining the charges. Find the minimum initial velocity of the proton that will allow it to escape to infinity. Ignore gravitational or any other influences on the proton.
