Aperson with mass mp = 76 kg stands on a spinning platform disk with a radius of r = 1.98 m and mass md = 191 kg. the disk is initially spinning at ω = 1.7 rad/s. the person then walks 2/3 of the way toward the center of the disk (ending 0.66 m from the center). if the person now walks back to the rim of the disk, what is the final angular speed of the disk?

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.
