Question
α-particles are projected towards the nucleus of following metals with the same kinetic energy. Towards which metal, the distance of closest approach will be minimum?
Options
A.Cu (Z = 29)
B.Ag (Z = 47)
C.Au (Z = 79)
D.Ca (Z = 20)
Solution
For rmin, q2 = nuclear charge and hence, z should be minimum.
