A 6.7 kg box is being pulled across the floor with a force of 186 N. If the box is accelerating at 2.89 m/s2, what is the frictional force?
Draw a diagram showing ALL forces acting on the box and show ALL your work to solve
the problem.

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.
