Help ME... A baseball player exerts a force of 100N on a ball for a distance of 0.5m as he throws it. If the ball has a mass of 0.15kg, what is its velocity as it leaves his hand?
−36.5m/s
−25.8m/s
25.8m/s
36.5m/s

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.
