 minima occurs at , x = begin mathsize 12px style open parentheses n plus 1 half close parentheses fraction numerator lambda D over denominator d end fraction end style  , n = 0, ±1, ±2.....
where d is distance between slits and D is distance between slits and screen

for first minima n = 0,  hence x = begin mathsize 12px style 1 half fraction numerator lambda D over denominator d end fraction end style = D    hence  2d = λ
we are given that d = 2D  , hence  4D = λ   or  D = λ/4

CBSE 12-science - Physics
The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
