what is the moi of a uniform cube about an axis which passes through centre
my thinking:
a rod's moi about centroidal axis is (ml^2)/12
a square plate is just integration of multiple rods of same moi therefore moi of square plate about x or y axis is also (ml^2)/12 ...
If we make gaussian surface around a dipole, net charge inside the surface will be zero so electric field should be zero, but dipole has an electric field.....
actually i want to study thermodynamics in deep out of
Bruce H. mahan , Peter Atkins and Mc murry -fay
what should i choose for deep understanding (self study via book reading :)) my style )...
