Question

SECTION 2 cero? Answer on the ine given here, and oso skertch on the digram above the Angstroms (d) What is the vakue of the potential V at a point on the positive y axis, aty Angstroms? Answe in the above diagram, I have placed an electron (charge -e) at the origin. The grid spacing is Angstrom, or 10m. Now place an atomic ucleus of positive charge L26(that i E.26 times the change of a single proton or electron) on positive x-axi, atxEe Angstroms. Now answer the following questions: (a) How much work did it take you to bring this nucleus in from very far away and place it onthe positive Nais atx.L b-5 Angstroms? (el How much work would it take to bring in another atomic nucleus of positive charge from very far away and place it at this point on the positive yaxis at ya Angstroms? (b) There will be a place on the x-axis where the total electric feld due to the two charges is zero. At what value of x will this oceur?
