The center of mass of a 0.20 kg (non-uniform) meter stick is located at its 46-cm mark. what is the magnitude of the torque (in n⋅m) due to gravity if it is supported at the 29-cm mark? (use g = 9.79 m/s2).

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.
