What should be the indication on the magnetic compass as you roll into a standard rate turn to the right from a northerly heading in the northern hemisphere?
a) the compass will indicate the approximate correct magnetic heading if the roll into the turn is smooth. b) the compass will remain on east for a short time, then gradually catch up to the magnetic heading of the aircraft. c) the compass will initially indicate a turn to the left.

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.
