A golf ball is launched at an angle of 45o. The ball has an initial vertical velocity of 12 m/s and an initial
horizontal velocity of 12 m/s. Forget air resistance. The ball reaches its maximum height 1.2
seconds after it is launched and lands at the same height that is launched from. The total
horizontal distance reached by the golf ball is about

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.
