Which of the following is a true statement?
a. electric fields increase in strength as you move farther from the charge, but electric forces decrease.
b. both electric fields and forces decrease in strength as the distance increases.
c. electric fields don't change in strength with distance from a charge, but electric forces do.
d. electric forces stay the same as distance changes, but electric fields change.

The system's potential energy is

Explanation:

The total mechanical energy of the system is E which the sum of the potential energy and the kinetic energy.

The total energy of a simple harmonic oscillator is given as E = .

The system's kinetic energy is given as

Total system Energy (E) = Potential Energy (P) + Kinetic Energy (K)

                                  E = P+K

                                  P = E - K

                                   P =

                                   P = =

   Potential Energy (P) of the system =
