Problem 2 A LC circuit is measured to have a maximum current of 4A. The circuit contains a 4µF capacitor and a 1/(2π) 2 H inductor. The capacitor is fully charged at t = 0 a) Find the maximum charge of the capacitor b) Find the time which the capacitor is discharged charged for the first time (regardless of direction) c) What fraction of the circuits energy

If the spring constant k of a pogo stick is 3500 n m and the weight of the person on the pogo stick is 700 n, how much is the spring in the botom of the pogo stick compressed?

Athin nonconducting rod with a uniform distribution of positive charge q is bent into a circle of radius r. the central perpendicular axis through the ring is a z-axis, with the origin at the center of the ring. a) what is the magnitude of the electric field due to the rod at z = 0? n/c (b) what is the magnitude of the electric field due to the rod at z = infinity? n/c (c) in terms of r, at what positive value of z is that magnitude maximum? r (d) if r = 4.00 cm and q = 9.00 µc, what is the maximum magnitude? n/c
