- 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 2.33 x 104 N/C. m/s? (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.Three identical charged particles, with an inertia of 0.75 mg carrying +1.5\muC, are held in place formingan equilateral triangle separated by 250 nm. The particles are simultaneously released from rest andbegin to move. How fast is each particle moving when the particles are separated by 750 nm?An electron has an initial velocity of 3×10to6 m/s in the +x direction. It enters a uniform electric field E = 418 N/C which is in the +y direction. By how much, and in what direction, is the electron deflected after traveling 11 cm in the +x direction in the field? (Express the direction of deflexion by using positive and negative signs. Your result must be in cm's and include 1 digit after the decimal point. Maximum of 5% of error is accepted in your answer. Take elementary charge 1.6x10to-19 C and mass of electron 9.1x10-31 kg.)

Find the force (magnitude and direction) between them (use L >> r and assume uniform force per unit length. Can you use the simple equation F=QE ?). Would you be able to feel this force if the rods are 1 meter long?An ink jet printer works on charged ink drop getting deflected as shown by an E field between 2 metal plates. An ink drop of mass 1.9 x 10-10 kg with a negative charge - 1.0 x 10-13 C initially moving along X -axis at speed 13 m/s and lenth of each plate is 1.8 cm. Assume uniform E field between the plates of 1.8 x 106 V/m. What is the vertical deflection distance y of the drop in mm?

Assume that the field between plates is zero. The electron enters the field at a point midway between the plates. (a) If the electron just misses the upper plate as it emerges from the field, find the magnitude of the electric field. (b) Supposed that the electron is the replaced by a proton with the same initial speed v0. Would the proton hit one of the plates? If not, what would be the magnitude and direction of its vertical displacement as it exits the region between the plates?In the classic model of the hydrogen atom proposed by Niels Bohr, the electron rotates around a stationary proton in a circular orbit with an approximate radius r = 0.053 nm, see the figure below.
