Consider a charge Q1(1+5.0C) fixed at a site with another charge Q2 (Charge +3.0C , mass 6.0g ) moving in die neighboring space, (a) Evaluate die potential energy of Q2 when it is 4.0 cm from Q1 (b) If Q2 starts from rest from a point 4.0 cm from Q1what will be its speed when it is 8.0 cm from Q1 ? (Note: Q1 is held fixed in its place.)
Consider two conducting spheres with radii R1 and R2 separated by a distance much greater than cither radius. A total charge Q is shared between the spheres. We wish to show that when the electric potential energy of the system has a minimum value, the potential difference between the spheres is zero. The total charge Q is equal to q1 + q2, where q1 represents the charge on the first sphere and q2 the charge on the second. Because the spheres are very far apart, you can assume the charge of each is uniformly distributed over its surface. (a) Show that the energy associated with a single conducting sphere of radius R and charge q surrounded by a vacuum is UE = keq2/2R. (b) Find the total energy of the system of two spheres in terms of the total charge Q, and the radii and R1 and R2. (c) To minimize the energy, differentiate the result to part (b) with respect to q1 and set the derivative equal to zero. Solve for q1 in terms of Q and the radii. (d) From the result to part (c), find the charge q2. (e) Find the potential of each sphere. (f) What is the potential difference between the spheres?
