An electron is observed traveling at a speed of 2.38 107 m/s parallel to an electric field of magnitude 11,460 N/C. How far will the electron travel before coming to a stop? (The mass of electron is 9.109 x 10-31 kg, and the charge on the electron is 1.602 x 10-19 C. The electron is moving in the direction opposite to the electric field.)
A thin, flat washer is a disk with an outer diameter of 14 cm and a hole in the center with a diameter of 3 cm. The washer has a uniform charge distribution and a total charge of 8 nC. What is the electric field on the axis of the washer at a distance of 28 cm from the center of the washer? (Enter the magnitude of the electric field.)
A) A massless rope connects two blocks (2.00 and 4.00 kg) over a 12.0 diameter, 2.00 kg pulley if the 4.00 kg block is 1.00 m above the surface what is the linear acceleration of the blocks when released, if there is a frictional torque of 0.500 Nm on the pulley?
B) Knowing the final velocity of the 2.00 kg block, what maximum height above the surface does it reach?
