Unformatted text preview: 1 . [1 point, 10 tries] An electron has a velocity of 1.3210 4 m/s (in the positive x direction) and an acceleration of 1.7710 12 m/s 2 (in the positive z direction) in uniform electric and magnetic feilds. If the electric field has a magnitude of 19.5 N/C (in the positive z direction), what is the y component of the magnetic field in the region? Answer:-2.24e-03 T- 2 . [1 point, 10 tries] In the figure below, the cube is 42.8 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 = 0.0199 T is in the positive y direction. Determine the magnitude of the magnetic force on segment ab . Answer: 0.0 N- 3 . [1 point, 10 tries] Determine the magnitude of the magnetic force on segment cd . Answer: 4.22E-02 N- 4 . [1 point, 10 tries] A long piece of wire of mass 0.139 kg and total length of 4.06 m is used to make a square coil with 66 turns. The coil is hinged along a horizontal side, carries a 3.98 A current, and is placed in with 66 turns....
