Transcribed Image Text:

The charges on three identical metal spheres are -12.6 μC, 4.20 μC, and 2.10 UC. The spheres are brought together so they simultaneously touch each other. They are then separated and placed on the x and yaxes, 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 4.20mm 4.20mm (a) Number 43 (b) Number Units N Units # The charges on three identical metal spheres are -12.6 μC, 4.20 μC, and 2.10 UC.
