A boy recalls the relation for relativistic mass (m) in terms of rest mass `(m_(0))` velocity of particle v, but forgets to put the constant c (velocity of light). He writes m= `(m_(0))/((1-v^(2))^(1//2))` correct the equation by putting the missing 'c'.

Text Solution

Verified by Experts

Since quantities of similar nature can only be added or subtracted, `v^(2)` cannot be subtracted from 1 but `v^(2) // c^(2)` can be subtracted from 1 .
`:. m = (m_(0))/(sqrt(1-v^(2)//c^(2)))`
