Aspring is stretched to a displacement of 3.4 m from equilibrium. then the spring is released and allowed to recoil to a displacement of 1.9 m from equilibrium. the spring constant is 11 n/m. what best describes the work involved as the spring recoils?

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.
