In one model of the hydrogen atom, the electron revolves in a circular orbit of radius 5.3 x 10-11 m. Calculate the speed of the electron.
Shown are the configuration of a gel electrophoresis experiment. Charged plates establish an electric field on a region of gel between the plates. A solution of DNA fragments, which acquire a negative charge in solution, is analyzed by using an electric field to drive the fragments through the gel. A drag force opposes the motion, causing the fragments to move at a constant speed. Larger fragments move more slowly, so the fragments separate by size to give a “fingerprint” of the sample. The fragments move in the direction of _________ electric potential and __________ electric potential energy.A. higher, higherB. higher, lowerC. lower, higherD. lower, lower
A positively charged particle of mass 1.92 x 10-27 kg initially moves left to right long the x axis at a speed of 4.02 x 103 m/s. It moves into an electric field, which points in the negative x direction, and travels a distance of 0.41 m before coming to rest. What acceleration magnitude does the particle experience? (Ignore gravity) Round your answer to 2 decimal places.
A positive point charge Q is fixed on a very large horizontal frictionless tabletop. A second positive point charge q is released from rest near the stationary charge and is free to move. Which statement best describes the motion of q after it is released? As it moves farther and farther from Q, its speed will keep increasing. Its speed will be greatest just after it is released. As it moves farther and farther from Q, its acceleration will keep increasing. As it moves farther and farther from Q, its speed will decrease. Its acceleration is zero just after it is released.

A proton is accelerated horizontally from rest by a voltage U 1 = 1.0 kV and enters a homogeneous electric field between two parallel and electrically charged plates. The voltage between the plates is U2 = 4.0 kV and the distance between them is 10 cm. We disregard all forces other than the electric power. a) Calculate the starting velocity of the proton and describe the motion that the proton gets when it enters the electric field between the plate. b) Calculate out the stretch as the proton will move horizontally before hitting one of the plates.

A positive point charge Q is fixed on a very large horizontal frictionless tabletop. A second positive point charge q is released from rest near the stationary charge and is free to move. Which statement best describes the motion of q after it is released? As it moves farther away from Q, its acceleration will remain constant but its speed will increase. As it moves farther away from Q, its acceleration will decrease but its speed will increase. As it moves farther away from Q, its acceleration and speed will decrease. As it moves farther away from Q, its acceleration and speed will increase.
