A non-uniform rod AB has a mass M and length 2l.The mass per unit lengthof the rod is mx at a point of the rod distant x from A. find the moment of inertia of this rod about an axis, a)through A,b) through the mid point of AB. Ans) let a element of length dx at adistance x from the point A of the rod.mass of this element will be dm = mxdxso moment of inertia of this element about point A is dI = dm * x2for moment of inertia of whole rod perform intigrationI= ∫dI = o∫2Ldm * x2 =o∫2Lm * x3 dx =4mL4and we know M =o∫2Ldm = o∫2Lmxdx =2mL2so moment of inerta I =2ML2
Lyman series: The series which define the emission spectrum of hydrogen while electrons are jumping to the ground state. All lines are in the ultraviolet.
An atom is said to be polarized if it possesses and effective dipole moment, that is, if there is a separation between the centres of negative and positive charge distribution. It
