written Problem 1: problem is worth a total of 30pts.) (This Three point charges are arranged in an equilateral triangle as seen below +4.0 C 1.20 m 8.0 6.0 PwC Find the net horizontal component of the electric field at the center of the triangle. .5pts. 14000 Answer b) Find the net vertical component of the electric field at the center of the triangle. (7.5pts.) Answer Answers d) If an electron was brought from infinitely far away to the center of the triangle, how much work s has been done by the electric force (7.5pts.) worr dont q sed 3,312 10 Answer 2.12 MD isExplanation / Answer
As you have not specified the parts for which you need answer, I have answered 4 questions:
Q.1 F = qE
q = F/E= 7 x 10^-5/ -20 = -0.35 x 10^-5 = - 3.5 x 10^-6 C ( correct option is c)
Q.2 Electric field inside the conductor is 0, as the entire charge redides on the surface. ( correct option is b)
Q.7 The current arrangement will have strong force of attarction between alpha and electron, therefore electron must be placed to the right of electron so as to minimize the force of attarction between aplha and electron and to maximize the force of repulsion between two electrons, ( therefore correct option is b)
Extra credit (Q.1) elecrostatic force of attraction between proton and electron
and motion are perpendicular , therefore work done will be 0
