Math Problem Statement
Points P , Q and R are located in an electric field set up by a set of charges that are fixed in three-dimensional space. A test charge of 5 C is being transferred from point P to point R via point Q. During the transfer from point P to point Q, 10 J of work is done by the electric field. During the transfer from point Q to point R, 20 J of work is done against the electric field. VPQ = electric potential difference between point P and point Q VQR = electric potential difference between point Q and point R VRP = electric potential difference between point R and point P. The above three potential differences are written using the double subscript notation. Question 1 Answer a. VPQ = -2 V and VQR = -4 V and VRP = 2 V b. VPQ = 2 V and VQR = -4 V and VRP = -2 V c. VPQ = 2 V and VQR = -4 V and VRP = 2 V d. All of the other statements are incorrect
