Two identical beads each have a mass m and charge q. When placed in a hemispherical bowl of radius R with frictionless, non-conducting walls, the beads move, and at equilibrium they area distance R apart (figure). Determine the charge on each bead.

Two identical small balls each have a mass m and charge q. When placed in a hemispherical bowl of radius R with frictionless, nonconductive walls, the bead move, and at equilibrium the line joining the balls is horizontal and the distance between them is R (see figure). Neglect any induced charge on the hemispherical bowl. Then the charge on each bead is : (here K=(1)/(4piepsilon_(0)) )

Two point charges, each of mass m and charge q are released when they are at a distance d from each other. What is the speed of each charged particle when they are at a distance 2r ?

Four identical point masses , each of mass m and carrying charge +q are placed at the comes of a square of sides a' on a frictionless plain surface .If the particles are released simulataneously ,the kinetic energy of the system when they are infinitcly far apart is

Two identical metal spheres A and B have equal and similar charges. They repel each other with a force 103N, when they are placed 10cm apart in a medium of dielectric constant 7. Determine the charge on each sphere.

A rigeid insulated wire frame in the form of a right-angled traingle ABC is set in a vertical plane as shown in fig. two beads of equal masses m each and carrying charges q_(1) and q_(2) are connected by a cord of length l and can slide without friction on the wires. Cinsidering the case when the beads are stationary, determine (i) the angel alpha (ii) the tension in the cord, and (iii) The normal recation on teh beads. If the cord is now cut, what are the value of the charges for which the beads continue to remain stationary?
