- Two electrons are fixed 1.70 cm apart. Another electron is shot from infinity and stops midway between the two as the figure shows. What is its initial speed?The next 5 questions all have to do with the diagram shown, on which I have placed an electron at the origin. The grid spacing is 1 Angstrom per small square. Now place an atomic nucleus with 20 protons on positive x-axis, at x = 6.4 Angstroms. How much work did it take you to bring this nucleus in from 1 m away? 45.0 eV 27.0 eV 58.5 eV 36.0 eV(a) What is the electric potential energy of two electrons separated by 1.94 nm? (b) What would be it be if the separation was doubled?
- How many volts of potential difference is required to stop the electron with an initial velocity of 4.2 x10 ^ 5m / s?(qe = -1.6x10 ^ -19 c: m = 9.11x10-31 kg)In the figure below, determine the point (other than infinity) at which the electric field is zero. (Let q, = -1.65 µC and q2 = 6.90 µc.) -1.00 m-A parallel plate capacitor has a charge on one plate of q = 1.1E-06 C. Each square plate is d1 = 1.9 cm wide and the plates of the capacitor are separated by d2 = 0.65 mm. The gap is filled with air, εo = 8.85 × 10-12 C2/Nm2. What is the voltage between the plates, ΔV, in V?

Determine the final speed of the mobile electron when it is far away from the fixed one.Homework Question 13. A proton is shot at the nucleus of a gold atom. When the proton is a long way from the atom, its speed is 6 x106 m/sec. How far from the center of the nucleus is the turning point of the proton? (There is a periodic table in the appendix of your book.)The next 5 questions all have to do with the diagram shown, on which I have placed an electron at the origin. The grid spacing is 1 Angstrom per small square. Now place an atomic nucleus with 5 protons on positive x-axis, at x = 2.1 Angstroms.

- As shown in Figure 1, two parallel plates have a potential ditterence of 12 V and are held a distance of 0.001m apart. A free charge held near the positive plate moves to the right, as shown, when it is released. It then moves through an opening in the negative plate on the right. 12V (a) Is the particle a proton or an electron? (b) What is the energy (in Joule) as it leaves the right plate? (c) How fast is it moving when it reaches the negative plate? (d) What are the magnitude and the direction of the electric field between the plates?An electron initially at rest, is allowed to accelerate through a potential difference of 1 V, gaining kinetic energy KEe, whereas a proton, also initially at rest, is let accelerate through a potential difference of 1 V, gaining kinetic energy KEp. As ∣qe∣ = ∣qp∣ but mp >> me, therefore, Group of answer choices KEe >> KEp KEe << KEp KEe = KEp All we can say, is KEe ≠ KEp10. Metal tube of infinite length and square cross-section with sides 0 ≤x≤L, 0 ≤ y ≤ L has three of its sides at potential zero and the fourth (y=L) in potential U. It is requested to determine the potential at inside the tube. Assume that along the contact lines of between surfaces with different potential there is a thin insulating material.
