A coil of area 15cm^2 is placed in a uniform magnetic field of strength 0.5T. the. coil has 150 turns and a resistance of 5ohms. it is supplied with a current of from a 9volt cell. calculate the maximum torque exerted in the coil. ​

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.
