Using equation 3 in 2 we get E = pc --------------- (4)
Energy of the photon is given as 1 eV (1 eV = 1.6 x 10
-19
J). As energy is given in eV, we need to
convert it into Joules (as Joule is the SI unit of energy).
Putting the values in equation 4 we get p = 5.33 x 10
-28
kgms
-1
Hence, D is the correct answer option.
