Document Summary
Two charges, +q and 2q, are separated by a distance d. calculate x andy components of the electric field at point p which is a distance b above the negative charge. A capacitor with capacitance c is charging by a battery v through a resistor r. the switch is closed at t=o. The self-inductance of the circuit can be ignored. 1dr n_a: find the charge on the capacitor as a function of time. C\i-. -i o: find the current i into the plates and the displacement current. Calculate the displacement current through the flux of the electric field. Problem 4: (18 points: a non-uniform, but spherically symmetric, distribution of charge has a charge density p(r) given as follows: p(r)=p0(l 4ri3r) for rr p(r)=o for rr where p0 is a positive constant. L - g3: consider a parallel plate capacitor with area a and distance d between the plates.
