3) (1 pt) An image of some equipotential lines is shown below. Lines are labeled in units of volts. i. If \( a+1 C \) charge is moved from point \( Q \) to point \( R \) to point S, the total net work done on it is closest to A. 0 B. \( +0.15 \mathrm{~V} \) C. \( -0.15 \mathrm{~V} \) D. \( +0.65 \mathrm{~V} \) E. \( -0.65 \mathrm{~V} \) ii. There are charges located at points A, B, and C. Their signs are A. All positive B. All negative C. A and B positive, \( C \) negative D. \( A \) and \( B \) negative, C positive
