PART (1) Assume capacitor is fully charged when switch is at position 'a' for about 10 minutes. The switch is changed to position 'b' at t= 0. What is the current in the circuit immediately after the switch is closed? Assume after some time, the current in the circuit is 80.0 mA when the switch is at position 'b'. Can you find, what will be that time? 9.0 V 부 Paragraph a itur b 1.0 με PART (II) Assume a magnetic field of 5.2 T present inside the cyclotron.

Instructions 50 cm 10 cm 8.0 A R = 1.0 × 10-3 N A small circular loop of wire of radius 5 cm and resistance 1E-3 Q is centered inside a large circular loop of wire of radius 50 cm. The larger loop, which initially carries a current of 8 A, is cut and its current is reduced to zero over a time interval of 1E-6 s. Our goal will be to find the average current in the smaller loop during this time interval. (The magnetic field of the larger loop is approximately constant over the smaller loop.)

In the figure below the blue wire has a current I = 31 A. And the red loop is a square with sides that are 28 cm long the distance between the blue wire and wire AB is 3.6 cm determined to force the blue wire exerts on AB and the force the blue wire exerts on CD
2. A 0.30-m-long metal bar is moving to the left at constant speed of 20 m/s perpendicular to a uniform 2.0 T magnetic field. The bar rides on parallel metal rails connected through a 6.00 resistor, so the apparatus makes a complete circuit, as shown in the figure below. Ignore the resistance of the bar and the rails.
