Nan oscillating lc circuit, l = 3.76 mh and c = 3.13 μf. at t = 0 the charge on the capacitor is zero and the current is 2.95 a. (a) what is the maximum charge that will appear on the capacitor? (b) at what earliest time t > 0 is the rate at which energy is stored in the capacitor greatest, and (c) what is that greatest rate?

Part a)

Part b)

Part c)

Rate of energy = 301.5 J/s

Explanation:

Part a)

Since energy is always conserved in LC oscillating system

So here for maximum charge stored in the capacitor is equal to the magnetic field energy stored in inductor

now we have

Part b)

Energy stored in the capacitor is given as

now rate of energy stored is given as

so here we also know that

now from above equation

so maximum rate of energy will be given when

Part c)

Greatest rate of energy is given as

all of the answers are correct.

falsification is manipulating research materials, equipment, or processes or changing or omitting data or results such that the research is not accurately represented in the research record. plagiarism is the appropriation of another person's ideas, processes, results, or words without giving appropriate credit.

explanation:

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
