Unformatted text preview: Physics ZB-Section B Electriclty and Magnetism I”? Prof. luan K. Schuller Winter 2006 TEST l MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. 1) A very long wire has a line charge density of 7.0 nC / m. What is the electric ﬁeld strength 3.0 m from the center of the wire at a point on the Wire's perpendicular bisector? (The value of k is 9.0 x 10 9 N-m2/ C2.) A) 14N/C B)21N/C C)4.7N/C D)42N/C Figure +0.600 11C -0.900 [JC 2) In the Figure , a small spherical insulator of mass 12 x 10—2 kg and charge +0.600 [1C is hung by a thin wire of negligible mass. A charge of —0.900 11C is held 0.150 m away from the sphere and directly to the right of it, so the wire makes an angle 0 with the vertical (see drawing). What is the angle 6 ? A) 180" B) 10.4" C) 11.7° . D) 21.2“ E) 15.6° 3) Two like charges of the same magnitude are 7.0 km apart. If the force of repulsion they exert upon each other is 5.0 N, what is the magnitude of each charge? (The constant of proportionality for the Coulombic force is 9.0 x 109 N-m2/ C2.)
