Consider an object of mass 78.3kg. Assume that it’s made up of equal numbers of protons, neutrons, and electrons. Youve separated the boxes of protons and electrons by a distance of 65 m. If you were to release the clump of protons from their box, how much acceleration would the clump of protons undergo due to its attraction to the clump of electrons in the other box?

In that same diagram, suppose that the field has a strength of 0.00298 T, and that the particle making track A moves at 847 m/s with a charge of absolute magnitude 1.6 x 10-19 C and a mass of 9.11 x 10-31 kg.  If the field were large enough for particle A to make a complete circle, what would you calculate for its diameter? Express your answer in millimeters (mm) and in normal notation.

Consider an electron, of charge magnitude e = 1.602 × 10-1⁹ C and mass m₂ = 9.11 × 10-31 kg, moving in an electric field with an electric field magnitude E = 4 x 10² N/C, similar to what Thana observed in the simulation. Let the length of the plates be L = 50 cm, and the distance between them be d = 20 cm. Find the maximum speed, v, the electron could be moving if it enters the space halfway between and parallel to the two plates to just barely strike one of the plates. m/s If the field is pointing upward, which plate will Thana conclude the electron strikes at this speed? O The upper plate, because the electron charge magnitude is positive. O The upper plate, because we are only considering the magnitude of the electron charge, and magnitudes are always positive. O The lower plate, because the electron is attracted to the negative plate. O The lower plate, because the electron is negatively charged.

Problem 3.13 The gravitational force between two masses is F = −G (M₁ M2/r²) and the electrostatic = -k (Q1 Q2/r²). (a) Show that all massive objects attracted to force between two opposite charges is F the Earth will have the same acceleration independent of mass. (b) Show that two charged objects attracted to a point charge Q will not have the same acceleration unless both have the same charge to mass ratio.

Problem #1: Old televisions work by accelerating electrons inside of a large vacuum tube. When the electrons hit the fluorescent screen at the front they are moving so fast that they give off light. An electron needs to be going at a speed of 108 m/s to give off light, but suppose at one point in the tube the electron is only at 107 m/s, so it needs to be accelerated. The acceleration is provided by a pair of charged wire meshes. (The holes in the mesh are big enough to allow the electron to pass through.) The meshes are 10cm apart; the first mesh is at a potential Va, the second one is at a potential Vb. 10 m/s 10cm a Fluorescent screen A) Calculate the potential difference Va-Vb that will allow the electron to get from the initial speed of 107 m/s to the needed speed of 108 m/s, as it passes from the first to the second mesh. Be sure to consider and explain the sign of your answer. B) Find the average electric field between the meshes. If you don't have an answer for part A, give…

The deflection of a particle beam depends on the charge to mass ratio: (D ~ q / m).   An electron beam, with q/m = –1.76 × 1011 C kg–1, deflects to –10 cm.   What is the deflection of a proton, p+?   Question 3 options:   > +10 cm   < +1 cm   < –1 cm   Question 4 (1 point)                   Which particle has the greatest deflection in the same electric and magnetic fields?   Question 4 options:   q/2 and 2m   2q and m   q and m

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?

In the Rutherford model of the hydrogen atom, a proton (mass M, charge Q) is the nucleus and an electron (mass m, charge q) moves around the proton in a circle of radius r. Let k denote the Coulomb force constant (1/4TTE0) and G the universal gravitational constant. The ratio of the electrostatic force to the gravitational force between electron and proton is: O kMm/GQq O kQq/GMm O GQq/kMm O GMm/kQq O kQq/GMmr²
