I have placed an electron at the origin. The grid spacing is 1 Angstrom per small square. You have a nucleus with 5 protons at x = 7.8 Angstroms on the x-axis. What is the value of the electrostatic potential V at a point on the positive y-axis, at y = 5.6 Angstroms?     -2.6 V     7.5 V     3.9 V     4.9 V

Q-2: Two concentric conducting spherical shells of radii r¡ and r, > rz. The inner shell carries a charge +Q while the outer shell carries a charge +2Q as shown. Assuming V = 0 as r → ∞, Calculate: a. The electric field vectors: E1(r r2) b. The electric potentials: V, (r r2) c. The electric potential difference between the two shells: AV

Now you have a nucleus with 19 protons, placed at x = 5.1 Angstroms. What TWO values of x (along the x-axis) will the total electrostatic potential V be equal to zero?     0.28 Angstroms and -0.26 Angstroms     -0.11 Angstroms and 0.08 Angstroms     0.11 Angstroms and -0.08 Angstroms     -0.28 Angstroms and 0.26 Angstroms

Electron An electron and a proton are each moving at 4.80 x 105 m/s in perpendicular paths as shown in the figure. At the instant when they are at the positions shown in the figure, find the magnitude and direction of total magnetic field proton and electron produce at the origin. (e = 1.60 x 10-¹9 C)
