Applying electrostatic attraction Two small identical conducting spheres A and B are suspended on long silk threads as shown in the diagram. They carry charges of +3 nC and -2nc respectively. A: +3 nC B:-2 nC 1 Calculate the number of electrons that were transferred to B to acquire a charge of -2 nC. The spheres are allowed to move. 2 Describe in your own words the sequence of events that will occur. 3 Calculate the charge on B when it is stationary again. 4 Calculate the excess or deficit number of electrons on B. ​
