Can X-rays be deflected by gravitational force ? If yes, how?

answered-by-expert Expert Answer

x - rays consist of photons which are massless entities. so x - rays are unaffected by gravitational force.

But according to special theory of relativity, photons moving with very high speed are not massless. Gravitational force due to black hole can deflect the these photons.

The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
