Consider two positive charges Qi and Q2 of the same magnitude 5.5°C symmetrically placed on the c-axis at x = 3.6 cm". Consider a third positive charge Q3 of magnitude 9uC and mass 3 g moving along the y-axis. Where applicable, let the potential energy be zero when charges are very far apart from each other. What is the potential energy of Q3 when it is at y = 3.4 cm? If Q3 is released from rest at y =...

There are two identical, positively charged conducting spheres fixed in space. The spheres are 36.6 cm apart (center to center) and repel each other with an electrostatic force of F1 = 0.0615 N. Then, a thin conducting wire connects the spheres, redistributing the charge on each sphere. When the wire is removed the spheres still repel but with a force of F2 = 0.100 N. Using this information, find the initial charge on each sphere, q1 and q2 if initially...
