The figure below represents three charged metal spheres, A, B,andC, arranged so that line AB is perpendicular to line AC. Thechargeon A is +1 unit, on B +2 unites, and on C -6 unites. Thedistancebetween A and C is twice the distance between A and B. Allof thespheres are the same size.
a. If the magnitude of the force B exerts on A is F, whatisthe magnitude of the force that C exerts on a?
b. What is the magnitude of the resultant force exerted byBand C together on A?
c. If A were free to move, in what general direction woulditaccelerate?
d. If A, B, and C were placed in contact and thenseparated,what would be the magnitude and sign of the resultingcharge oneach sphere?
