- Two metal spheres, each of radius 3.4 cm, have a center-to-center separation of 2.5 m. Sphere 1 has a charge of +1.2 × 10-8 C; sphere 2 has a charge of -3.2 × 10-8 C. Assume that the separation is large enough for us to assume that the charge on each sphere is uniformly distributed (the spheres do not affect each other). With V = 0 at infinity, calculate in volts (a) the potential at the point halfway between their centers and the potential on the surface of (b) sphere 1 and (c) sphere 2.Illustrate only the following questions: Two identical, small insulating balls are suspended by separate 0.25 m threads that are attached to a common point on the ceiling. Each ball has a mass of 2 x 10-3 kg. Initially the balls are uncharged and hang straight down. They are then given identical positive charges and, as a result, spread apart with an angle 36° between the threads. Determine a) the charge on each ball and b) the tension in the threads.The charges on three identical metal spheres are -11.4 μC, 3.80 μC, and 1.90 μC. The spheres are brought together so they simultaneously touch each other. They are then separated and placed on the x and y axes, as shown in the figure. Treat the spheres as if they were particles. What is the net force ((a) magnitude and (b) direction) exerted on the sphere at the origin? Express the direction as an angle in the range (-180°, 180°) with respect to the positive x-axis direction. 92 91 4.90mm 4.90 mm 93 -- SUPPO (a) Number i Units (b) Number i Units
