Sphere 1 with radius R1 has positive charge q. Sphere 2 with radius 2.00R1 is far from sphere 1 and initially uncharged. After the separated spheres are connected with a wire thin enough to retain only negligible charge, (a) is potential V1 of sphere 1 greater than, less than, or equal to potential V2 of sphere 2? What fraction of q ends up on (b) sphere 1 and (c) sphere 2? (d) What is the ratio s1/s2 of the surface charge densities of the spheres?

Two short non-conducting rods of lengths L and 2L are aligned on the y-axis as shown below. The lower rod (-L < y < 0) has a negative linear charge density of -A. The upper rod (0 < y < 2L) has a positive linear charge density of +A. The magnitudes of the linear charge densities are the same such that -A = - (+1) Find the potential V for a point located on the x-axis at x = a due to the presence of both charged rods. Assume V = 0 at infinity. (Hint: Partial symmetry can be used to simplify the problem). +2L (0, 0) -L V-y

I have a question regarding charged particles, it is as follows: A charge +q is at the origin. A charge -2q is at x = 9.00 m on the +x axis. (a) For what finite value of x is the electric field zero? (b) For what finite values of x is the electric potential zero? (Note: Assume a reference level of potential V = 0 at r = ∞.)Smallest value of x: largest value of x:.

A spherical conductor with a radius of 73.5 cm has an electric field of magnitude 8.20 × 105 V/m just outside its surface. What is the electric potential just outside the surface, assuming the potential is zero far away from the conductor?
