Q1. The switch in the circuit below has been open for a long time and is then closed. If the values of the emf, resistances, and capacitance are = 12 V, R1 = 2.0 02, R2 = 6.0 0, and C = 5.0 /F, what is the charge stored by the capacitor a long time after the switch is closed? R1 WW R2 A. 15 uC B. 60 uC C 30 JC D. 45 /C E. 7.5 uC Q2. A current / flows around a continuous path that consists of portions of two concentric circles of radii a and a/2, respectively, and two straight radial segments. The point P is at the common center of the two circle segments. What is the total field B at P? a/2 a P Jdi X Oz A. B - Hulk Aa B. B _ _ Hok 4a C. B = Half 2a D. B = 2a E. None of the above
