Calculate the period T and the tension in the string F as a function of the angle. Compute the moment of inertia of this system for an axis that passes through the combined center of mass and is perpendicular to the plane of the rings.
A small metal bead, labeled A, has a charge of 29 . It is touched to metal bead B, initially neutral, so that the two beads share the 29 charge, but not necessarily equally. When the two beads are after that placed 5.0 apart, the force between the..
Two 18 cm diameter charged disks face each other, 25 cm apart. Both disks are charged to - 30 nC. What is the electric field strength at the midpoint between two disks.
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 ..
The only force acting on a 2.7 kg canister that is moving in an xy plane has a magnitude of 2.7 N. The canister initially has a velocity of 3.0 m/s in the positive x direction, and some time later has a velocity of 7.4 m/s in the positive y direct..
Two charged spheres are 8.45 cm apart. They are moved and the force on each of them is found to have been tripled. How far apart are they now.
