Ariver flows due east at 2.33 m/s. a boat crosses the river from the south shore to the north shore by maintaining a constant velocity of 9.76 m/s due north relative to the water. the river is 212 m wide. what is the velocity of the boat relative to shore? answer in units of m/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.
