Aspaceship is rising vertically from the ground at a rate of 8000 miles per hour. a radar is situated 6 miles away from the launch pad, and it is tracking the distance the spaceship is moving away from the radar. when the ship is 8 miles above the ground, how quickly is it moving away from the radar?

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.
