In general the total energy of a harmonic oscillator having of two parts, potential energy (P.E) and kinetic energy (K.E.), the former being because of its displacement from the mean position and latter due to its velocity. As the position and velocity of the harmonic oscillator are continuously changing, P.E. and K.E. also change but their sum i.e., the total energy (T.E) must have the similar value at all times.
a) A charge of 3X10 -4 Coulomb at P (1, 2, 3) and a charge of -10 -4 Coulomb at N (2, 0, 5) in a vacuum. We desire to measure the force exerted on second charge beacuse of firs

as flux = E.A and flux density is equal to flux/A then why A/A cannot e cancelled ?
How a CPH does stop or its speed decreases? Answer; it is a principle that Vc is stable thus that; gradV c =0 Thus, never V c increases or decreases.
