Question

Item 1 Part B Point charges q1 = + 2.00 C and What is the electric potental at point b Express your answer with the appropriate units. =-2.00 pC are placed at adjacent corners of a square for which the length of each side is 1.50 cm Point a is at the center of the square, and point b is at the empty corner closest to q2 Take the electric potential to be zero at a distance far from both charges 351x105 v Submit Correct My Answers Give Up Part c Apont charge a :-200C moves from point a to port b How much work is done ong, by the electric forces exerted by h and ga Express your answer with the appropriate units. Submit My Answers Gie Up Incorrect; Try Again; 3 attempts remaining

Explanation / Answer

Va = (9x10^9 x 10^-6 ) ( 2/r - 2/r) = 0

Vb = (9 x 10^9 x 10^-6)(2/sqrt(0.015^2 + 0.015^2) - 2 / 0.015)

Vb = -3.51 x 10^5 V

(C) W = -(-2 x 10^-6)(-3.51 x 10^5)

W = - 0.703 J
