The charge on a capacitor in an ideal LC oscillator with an angular frequency of 200 rad/s is given by
q=Q cos(ωt+ϕ).
At t = 0.800 ms, the charge is q = 5.00 μC and the current is i = 0.300 mA. We want the phase ωt + ϕ (the argument of the cosine function) at that time and then we want the phase constant (or phase angle) ϕ of the oscillator.
a. What is the value of the phase? ωt+ϕ=?
b.What is the phase constant (or phase angle) ϕ?

For part (c) of the Check Your Understanding 14.10 I got 1800
rad/s for the angular frequency, am I right? The book gives the
answer as 1.4 * 10^3 rad/s. Also for part (b) I got -pi/2 rad, but
the answer is pi/2 rad and -pi/2 rad. I'm not sure where the pi/2
came from. I've attached the problem below. Please don't solve the
example but the questions after it.

1. (30pt) LC Circuit and Simple Harmonic Oscillator (From $23.12 RLC Series AC Circuits) Let us first consider a point mass m > 0 with a spring k> 0 (see Figure 23.52). This system is sometimes called a simple harmonic oscillator. The equation of motion (EMI) is given by ma= -kr (1) where the acceleration a is given by the second derivative of the coordinate r with respect to time t, namely dr(t) (2) dt de(t) (6) at) (3) dt...

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
