Does a LC circuit exists? If yes,then by formula (tan of phase angle=reactance of inductor - reactance of capacitor/R)   what is the value of tan phase angle??

LC circuit means circuit with zero resistance.
 
This is not possible, because the inductor has some resistance R .
 
Hence only LCR circuit exsist
 
phase angle φ is given by,  tanφ = ( XC - XL ) / R
where XC is capacitive reactance, XC = 1/Cω  and XL is inductive reactance , XL = Lω
R is resistance of inductance coil

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?
