Under the action of a constant voltage U , a capacitor of capacitance C =10^(-11) F included in the circuit shown in Fig. 113 is charged to q_(1) = 10^(-9) C . The inductance of the coil, is L = 10^(-5) H , and the resistance of the resistor is R = 100 Omega . Determine the amplitude q_(0) of steadystate oscillations of the charge on the capacitor at resonance if the amplitude of the external sinusoidal voltage is U_(0) = U .

Two square metallic plates of 1m side are kept 0.01m apart, like a parallel plate capacitor, in air in such a way that one of their edges is perendicular, to an oil surface in a tank filled with an isulating oil. The plates are connected to a battery of e.m.f. 500 volt. The plates are then lowered vertically into the oil at a speed of 0.001 m//s . Calculate the current drawn from the battery during the process. [di-electirc constant of oil = 11, in_(0) = 8.85 xx 10^(-12) C^(2)//N^(2)m^(2)]

The well know mineral flourite is chemically calcium fluoride. It is a well known fact that in one unit cell of this mineral, there are four Ca^(2+) ions and eight F^(-) ions and Ca^(2+) ions are arranged in f.c.c. lattice. The F^(-) ions fill all the tetrahedral holes in the face centred cubic lattice of Ca^(2+) ions. The edge length of the unit cell is 5.46xx10^(-8) cm. The density of the solid is 3.18"g cm"^(-3) . Use this information to calculate Avogadro's number (Molar mass of CaF_(2)=78.0"g mol"^(-1) )
