Net force=
where is the elongation, L is original length, is the angular velocity
Substituting the equation of into the above we obtain
Black holes.
Although black holes don't have surface they are the only known object that has gravity that not even light can escape it.
Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2<span>) electrons.</span>
