In tangent galvanometer, the relation between current I and deflection θ is given as
 
I = k tanθ, where k is reduction factor.
 
when current is 1 amp and deflection is 30º. hence k = √3.
 
current for 60º is, I = √3×tan60 = √3×√3 = 3 amp

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?
