When the absorption or emission lines of a moving object away from from the earth at very high speed then the spectral lines will be shifted toward the red end of the spectrum.This effect can be easily understand by Doppler effect..

So the our option c is correct.

c. They will be shifted toward the red end of the spectrum.

Two positive charges are equal. Which has more electric potential energy?

Xelga [282]

Electrostatic potential energy of a system of charge is given by

$U = \frac{kq_1q_2}{r}$

here we have

$q_1,q_2$ = two charges of different magnitudes

r = distance between charges

so here we can see that electrostatic potential energy will depends upon the product of two charges and inversely depends upon the distance between the two charges

So here we can say that the electrostatic potential energy of two charges will be same and equal to each other
