Q. A 45.50 cm diameter disk rotates with a steady angular acceleration of 2.00 rad/s2. It starts from rest at t = 0, and a line drawn from the center of the disk to a point P on the rim of the disk makes an angle of 57.30° with the positive x-axis at this time.

Q. Apply Faraday's Law to show that the static electric field between the plates of a parallel-plate capacitor cannot drop abruptly to zero at the edges but must, in fact, fringe.
