12) How much work must be done to move a proton from point A, at a potential of –75V, to point B, which is at a potential of +25 V, along the curved path shown in the figure? Assume the system is isolated from any outside forces. (charge on a proton = 1.60 × 10¬19 C) -75V +25V A) 1.6 J B) 1.60 × 10-17 J C)-1.60 x 10-15 J D) –1.6 J E) Need to know the length of the curved path
