A1.2-kg mass is projected from ground level with a velocity of 30 m/s at some unknown angle above the horizontal. a short time after being projected, the mass barely clears a 16-m tall fence. disregard air resistance and assume the ground is level. what is the kinetic energy of the mass as it clears the fence

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.
