A famous relation in phyics relates the moving mass ` m` to the rest mass `m_(0)` of a particle in terms of its speed `v` and the speed of light `c`.( This relation first arose as a consequence of the special theory of relativity due to Albert Einstein). A body recalls the relation almost correctly but forgets where to put the constant `c` . He writes `m = (m_(0))/((1- V^(2))^(1//2))`. Guess where to put the missing `c`.

Explanation

The correct formula is `m=m^(0)(1-v^(2)//c^(2))^(-1//2)`
