Question
Please include work! I'm stuck on these problems and I'd like to know how to solve them.
1.) In the circuit in the figure below, assume the resistance value is R1 = 1,300 ohms, the capacitance is C1 = 65 uF, and the emf is = 5.5 V. The switch is labeled S. If the switch is closed for a very long time, what is the charge on the capacitor?
______C
2.) A rod of mass 0.720 kg rests on two parallel rails (see figure below) that are d = 12.0 cm apart and L = 45.0 cm long. The rod carries a current of I = 66.0 A in the direction shown and slides along the railswithout friction. A uniform magnetic field of magnitude 0.320 T is directed perpendicular to the rod and the rails. If it starts from rest, what is the speed of the rod as it leaves the rails?
_________m/s
Thank you so much for your help!

1 Q = Qo( 1- e-t/T) When time tends to infinity Q = Qo = CV = 65*10^-6 * 5.5 = 3.575*10^-4 COULOMB
