At what separation should two equal charges , 1.0 C each, be placed so that the force between them equals  the weight of a 50 kg person

answered-by-expert Expert Answer
Force due to charges F = (q1×q2)/ [ (4πε0) r2 ] ; q1 and q2 are charges in Coloumb. is permisibility in air/vacuum. r is the separation distance
 
we are given F = 50 kgf = 50×9.8 N ; q1 = q2 = 1C ;
 
1 / (4πε0) = 8.89×109 ;
 
hence 50×9.8 = 8.89×109 / r2 ; 
 
r2 = 8.89×109/(50×9.8) ; solving for r we get r = 4284 m

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?
