7.) A proton from an accelerator strikes an atom. An electron is
observed flying forward in the same direction
the proton was
moving and at a speed much greater than the
speed of the proton
What conclusion can you draw about the
relative mass of the
electron?

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.
