On a smooth horizontal table there is a metal rod of length L and mass m that can move across the table without friction. At one end of the rod is fixed a non-conducting thread that passes through an ideal pulley, fixed at the end of the table. At the other end of the thread hangs a rod exactly the same as the first. The system is then released and begins to move. Determine the potential difference that appears between the ends of each rod.

What is the capacitance of a planet that has mass (5.300x10^23) kg and a diameter of (7.9x10^6) m? Give your answer in farads (F) using scientific notation.

O West -1.36 x 10-3 J zero South A charge of 42.0 nC is placed in a uniform electric field that is directed towards the west direction and has a magnitude of 5.40 x 104 V/m. What work is done by the electric force when the charge moves a distance of 1.50 m in the direction 53° south of west? North -2.05 x 10-3 J 3.40 x 10-3 J East

As an electron moves through a region of space, its speed decreases from 9.60 × 106 m/s to 2.10 × 106 m/s. The electric force is the only force acting on the electron.       Across what potential difference did the electron travel?

A particle has a charge of +3.50 µC and moves from point A to point B, a distance of 0.130 m. The particle experiences a constant electric force, and its motion is along the line of action of the force. The difference between the particle's electric potential energy at A and B is EPEA - EPEB = +9.30 x 10-4 J. (a) Find the magnitude of the electric force that acts on the particle. (b) Find the magnitude of the electric field that the particle experiences. (a) Number i (b) Number Units Units

A package is at rest on a conveyor belt which is initially at rest. The belt is started and moves to the right for 1.3 s with a constant acceleration of 2 m/s?. Knowing that the coefficients of Coulomb friction between the package and the belt are 4, = 0.35 and µ = 0.25, determine: (a) whether the package slides during that 1.3s time interval; and (b) the work of the friction force on the package during that 1.3s interval.

The dielectric constants shown are κ1 = 1.0, κ2 = 2.0, κ3 = 3.0. The area of each plate is A = 0.20 m2, and the distance between the plates is d = 1.0 mm.
