- Part A An electron is moving east in a uniform electric field of 1.55 N/C directed to the west. At point A, the velocity of the electron is 4,52x105 m/s pointed toward the east, What is the speed of the electron when it reache: point B, which is a distance of 0.365 m east of point A? Express your answer in meters per second. ν ΑΣφ ve = m/s - Part B A proton is moving in the uniform electric field of part A. At point A, the velocity of the proton is 1.88x10 m/s , again pointed towards the east. What is the speed of the proton at point B? Express your answer in meters per second. Vp = m/s

What happens to the strength of the electric field of a single positive charge as the distance increases? What happens to the strength of the electric field of a single negative charge as the distance increases?

In the ever popular game from the future, Electrodisc, players can score double points by pushing a disc into another disc with the electric field generated by a third disc. The discs are by regulation 1 kg. All discs have the same shape and are made of the same conducting material. In the figure below, disc 1 is held in place, and disc 2 is held stationary 4.1 m from disc 1 by a player. The player then releases disc 2. 10 m. F12 What is the initial magnitude of the acceleration imposed on the second disc? The charge on the first disc is 1.7 mC. The charge on the second disc is 1.7 mC. The charge on the third disc is neutral. m/s² Later, discs 2 and 3 touch and charge is exchanged. How much charge is exchanged once the charges on each disc reach an equilibrium? mC After charge is exchanged, what is the direction of the force on disc 3 due to disc 2? O toward the left O toward the right O upward O downward

Part A and B

A uniform electric field of magnitude 45.1N/C is parallel to the x axis. A circular loop of radius 29.7cm is centered at the origin with the normal to the loop pointing 64.9∘ above the x axis. a. To what angle, in degrees from the positive x axis, should the normal of the loop be rotated so that the flux through the loop becomes 0.434N⋅m2/C?

Two 4.0 kgkg masses are 1.0 mm apart on a frictionless table. Each has 1.0 μCμC of charge.     Part A What is the magnitude of the electric force on one of the masses?   Part B What is the initial acceleration of each mass if they are released and allowed to move? Express your answer in meters per second squared.

3. A particle (q = 3.0 µC, m = 10 g) has a speed of 40 m/s when it enters a region where the electric field that has a constant magnitude of 100 N/C and the direction of the velocity with the electric field is 30 degree . What is the speed of the particle 5 s after it enters this region?

Protons of mass 1.68 x 1027 kg, traveling to the right with an initial velocity of 1 x 10° m/s, enter an electric field of 1x10 N/C directed into the plane of the page. The path followed by the protons is now: O the protons move at constant velocity into the plane of the page. O the protons are accelerated out of the plane of the page. the protons continue to move in a straight line to the right at velocity 1 x 10 m/s. O the protons are accelerated to the right. O the protons are accelerated into the plane of the page.
