In magnetic force on a current carrying wire" expriment using the data for force (y-axis, in newton) versus length in meters), someone obtained a linear curve fit countion: y=0.1x+2. if in the experiment, the wire carrying a current 2.0 ahow strong is the magnetic field? 2.0.1 t b. 0.05 t 2t d.0.2 t

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.
