6. A wire of length, 1 -04 m, parallel to the x axis moves in the x-y plane The B-field is parallel to the z-axis and points downward. Determine: (a) the induced emf in the wire; (b) the current in the wire if R 0.25 ohm. 7. A converging lens has a focal length, f 40 cm. If an object is placed at do 70 cm and whose height, ho 10 cm determine: (a) di; (b)m (c) h A charge, q =-5pC moves through a uniform B-field, B = 0.35 T, with a velocity, v 200 m/s, at right angles to the field. Determine: (a) Fm on the charge; (b) mass of the charge if a 5x 10 m/s. For the following circuit use the loop method to determine the current in each branch. 9. r2i ユ几 6vj 22 23n
