Created by StemPy LabTwenty-seven identical charged droplets are each at a potential of V. They join to form one large drop. What is the potential of the large drop?
← All Quizzes
← The graph shows how the potential changes along the x axis. In which part is the size of the field greatest, and in which direction does the field point there?Four small charges sit at the corners of a rectangle that measures 12 cm by 16 cm. They are +8.5 nC, +1.5 nC, -5.5 nC and -1.5 nC. What is the potential at the centre of the rectangle? →
