Give a specific example of a system with the energy transformation W→K . In this question, W is the work done on the system by the environment, and K and U are the kinetic and potential energies of the system, respectively. Any form of energy not mentioned in the transformation is assumed to remain constant. As part of your response, identify the objects that are in the system.

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
