A parallel plate capacitor with plate area 9.75 x 10* m' is moving with a speed of 35 m/s perpendicular a magnetic field B - 3.6 T. The electric field inside the plates is E = 170 N/C. Determine the magnetic force on the positive plate of the capacitor. x 10 ' N O 1.38 1.42 1.61 1.85 Two identical point charges (q= +4 x 10 C ) are fixed at opposite sides of a square of side 0.85 m. A test charge (qo = - 7.8 10 C ), with mass of 3.70 x 10 kg, is released from rest at one of the corners of the square. Determine the speed of the test charge when it reaches the center of the square U 454.1 m/s 409.6 m/s 384.7 m/s | 478.3 m/s | 496.7 m/s 298. 56 6) The circuit below is designed for a charge of 88 JC to pass through the 4 HF capacitor.
