उत्तर
The central sphere is nucleus where small spheres are electron moving in circular orbit around nucleus.
(a) There is positive charge on nucleus.
(b) Charge on proton is equal to +1.6 x 10-19 c and neutron is neutral so value of charge on nucleus is p x 1. 6 x 10-19 c where p is the number of proton in nucleus.
