A block of mass mi is on an inclined plane (angle θ above the horizontal) and is connected by a massless string going over a pulley to a hanging block of mass m2. (The pulley is at the top of the ramp.) Both blocks are held firmly in place (i. e the blocks are at rest). If the blocks are released from rest, determine the acceleration of the blocks if the coefficients of static and kinetic friction between the block 1 and the surface of the incline are μs and μk, respectively. If the problem has multiple answers, explore at least 2 of them.

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.
