When charges q_a,q_b,and q_c are placed respectively at the corners a,b,and c of a right triangle,the potential at the midpoint of the hypotenuse is 24 V.When the charge q_a is removed,the potential at the midpoint becomes 17 V.When,instead,the charge q_b is removed (q_a and q_c both in place),the potential at the midpoint becomes 13 V.What is the potential at the midpoint if both charges q_a and q_c are removed? A)11 V B)7.0 V C)6.0 V D)18 V E)17 V

Question

The potential at the midpoint with all charges is 24 V. Removing q_a drops the potential to 17 V, indicating q_a contributes 7 V. Removing q_b instead drops it to 13 V, indicating q_b contributes 11 V. Thus, removing both q_a and q_c (given q_a's 7 V contribution), and knowing q_b alone gives 13 V, the potential with only q_b is 13 V, matching option A.
