The RC circuit below includes a 12 V battery, a 6022 resistor and a 10 mF capacitor. (a) Show
the complete calculation of the initial charge current in the circuit. (b) Show the complete
calculation of the time constant for charging the capacitor. (b) Show the complete calculation
of the charge current after 6.0 s. (c) Show the complete calculation of the final charge on the
capacitor.

Aproton is projected into a uniform electric field that points vertically upward and has magnitude e. the initial velocity of the proton has a magnitude v0 and is directed at an angle a below the horizontal. (a) find the maximum distance hmax that the proton descends vertically below its initial elevation. you can ignore gravitational forces. (b) after what horizontal distance d does the proton return to its original elevation? (c) sketch the trajectory of the proton. (d) find the numerical values of hmax and dife = 500 n> c,v0 = 4.00 * 105 m> s,anda = 30.0°.
