Answer 1

Answer:

An α−α− particle of momentum 3.2×10−20kgms−13.2×10−20kgms−1 is projected towards the nucleus of an atom of an element. If the distance of closest approach of α-particle is 1.5×10−13m1.5×10−13m, then the atomic number of element is (Mass of α−α− particle = 4 amu, charge on electron = 1.6×10−191.6×10−19 coulomb, NA=6×1023NA=6×1023)
