Answer:
Explanation:
(a) This problem can be solved by using the formula for Compton effect

where h is the planck constant, Φ is the angle of the scattered photon, m is the mass of the particle (in this case we take an electron) and c is the speed of ligth.
By taking the wavelength of the scattered photon and by replacing we have

(b)

(c)
The energy is conserved, hence we have

that is, the sum of the kinetic energy of the scattered electron and the energy of the scattered photon is equal to the energy of the incident photon. By taking Ek we have

(d)

I hope this is useful for you

Answer:
away from each other
Explanation:
Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges. The size of the force varies inversely as the square of the distance between the two charges.
