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’.

Explanation

To correct the equation for relativistic mass, we need to ensure that the dimensions on both sides of the equation match. The original equation provided by the boy is:

\[ m = \frac{m_0}{(1 - v^2)^{1/2}} \]

### Step-by-Step Solution:
