(10% ) Problem 4: In a given coordinate systern shown at right, a particle with charge q 3.2 C sits at the origin. The coordinates of point A are (0, 5) m. The coordinates of point B are (5,0) m. The coordinates of point C are (5,5) m. The coordinates of point D are (5, -5) m. (5, 5) (0, 5) B (5, 0) D (5,-5) Otheexpertta.com 25% Part (a) How much work is done by the field in moving a proton from point A to point B in J?

a) ZERO , because charge at center have equal potential at both these positions....V=kq/r
dq=qdv
b) that would also be zero, reason for this is same as previously discussed
