We know that point is something which has no dimension ( length, breadth etc.) but has existence. As point has no dimension, it has no volume. Moreover, it has no mass.
Density(d) = Mass(m) / Volume(v) m = d * v m = 0 ( since v = 0 )
But we are given problems such as - “ A point mass of 5 kg is moving with velocity …” . Are these problems composed in right manner ? Is it possible for a point to have mass greater than 0 ?
