An electron is placed in a uniform electric field of 43 nN/C directed north created by two horizontal parallel plates that are 120 mm apart. The electron accelerates from rest, starting at the negative plate. What is the net force and acceleration acting on the electron? How long did it take the electron to get from one side of the plate to the other?

Newer automobiles have filters that remove fine particles from exhaust gases. This done by charging the particles and separating them with a strong electric field. Consider a positively charged particle + 1.5uC that enters an electric field with strength 4 x 10^6 N/C. The particle is traveling at 15 m/s and has a mass of 10^-9 g. What is the acceleration of the particle ? (Enter the magnitude only) 2.) what is the direction of the acceleration of the particle relative to the electric field?

On a typical clear day, the atmospheric electric field points downward and has a magnitude of approximately 110 N/C. Compare the gravitational and electric forces on a small dust particle of mass 3,1 x 10 g that carries a single electron charge. 1.1134 What is the acceleration (both magnitude and direction) of the dust particle? (Enter the magnitude in m/s.) magnitude m/s direction downward v

A simple and common technique for accelerating electrons is shown in the figure below, where a uniform electric field is created between two plates. Electrons are released, usually from a hot filament, near the negative plate, and there is a small hole in the positive plate that allows the electrons to continue moving. (a) Calculate the acceleration of the electron if the field strength is 3.45 x 104 N/C. m/s² (b) Why will the electron not be pulled back to the positive plate once it moves through the hole? O The force of gravity is too strong. O There is no field outside the plates. O The other side of the positive plate also has a negative charge.

Help me answer this question please. An electron is projected horizontally at a speed of 2.5 x 10*6 m/s between two plates. metal parallel I = 7.5 cm in length as shown in the figure below. The greatness of electric field is 130 N/C. Determined : a) Acceleration of the electron b) The time it takes to escape from the metal plates c) The final vector velocity of the electron as it escapes from the plates

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

A proton is projected in the positive x direction into a region of uniform electric field E = (-6.20 × 105) ↑ N/C at t = 0. The proton travels 7.90 cm as it comes to rest. (a) Determine the acceleration of the proton. m/s² magnitude direction -X (b) Determine the initial speed of the proton. m/s magnitude direction +X ✓ ✓ (c) Determine the time interval over which the proton comes to rest.

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.

Two particles, an electron and a proton, are initially at rest in a uniform electric field of magnitude 514 N/C. If the particles are free to move, what are their speeds (in m/s) after 43.2 ns? electron m/s proton m/s
