My notes of the charge q initially on a tiny sphere, a portion q is to be transferred to a second, nearby sphere. both spheres can be treated as particles and are fixed with a certain separation. for what value of q/q will the electrostatic force between the two spheres be maximized?

m

Explanation:

Given:

Initial charge on the tiny sphere=Q

Charge transferred from tiny sphere to another sphere=q

According to coulombs law the electrostatic force between the two spheres is given by

Where r is the fixed distance between them.

For getting maximum force we will differentiate the force with respect to q

Hence we calculated the the ratio for maximum force between them

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.
