Unformatted text preview: CAPA 8 1 . An electron has a velocity of 1.20×10 4 m/s (in the positive x direction) and an acceleration of 1.96×10 12 m/s 2 (in the positive z direction) in uniform electric and magnetic feilds. If the electric field has a magnitude of 18.3 N/C (in the positive z direction), what is the y component of the magnetic field in the region? Answer: 2 .In the figure below, the cube is 38.5 cm on each edge. Four straight segments of wire  ab , bc , cd and da form a closed loop that carries a current I = 4.95 A in the direction shown. A uniform magnetic field of magnitude B = 0.0191 T is in the positive y direction. Determine the magnitude of the magnetic force on segment ab . Answer: 3 . Determine the magnitude of the magnetic force on segment bc . CAPA 8 Answer: 4 . Determine the magnitude of the magnetic force on segment cd . Answer: 5 .Determine the magnitude of the magnetic force on segment da . Answer: 6 . A long piece of wire of mass 0.138 kg and total length of 4.47 m is used to make a square coil with 89 turns. The coil is hinged along a horizontal side, carries a 3.05 A current, and is placed in with 89 turns....
