Q. An electric field of 300 V/m is confined to a circular area d = 11.1 cm in diameter and directed outward perpendicular to the plane of the figure. If the field is increasing at a rate of 22.0 V/m·s, what are direction and magnitude of the magnetic field at the point P, 16.4 cm from the center of the circle?

Q. An object is 9 cm high and is located p = 29.2 cm in front of a thin diverging lens of focal length f = -18 cm. Calculate the position (distance from the center of the lens) and the height of its image.
