Correct Answer - `11.37 xx 10^(-4) m`
Correct Answer - C `0.03`= weight to Hb in mg xx `10//100` weight of Hb in mg `=0.30`
Correct Answer - 5 `K.E.=(KZe.2e)/(r ), " "K.E.=(9xx10^(9)xx29xx2(1.6 xx 10^(-19))^(2))/(1.67xx10^(-14))=5Mev`
Correct Answer - 1.008968u
Correct Answer - `4.3 xx 10^(-14)m` , the size of the nucleus cannot be greater than `4.3 xx 10^(-14)m`.
