1.	A boy recalls the relativistic mass wrongly as m=m_0/sqrt(1-v^2) Using dimensional method put the missing 'C' at proper place.
Answer» Solution :Here `[M]=[M_0]`. So the denominator MUST be dimensionless. Also `V^2` cannot be subtracted from the dimensionless CONSTANT 1. So `v^2`should be DIVIDED by `C^2` as to make it dimensionlessHence the CORRECT FORM of the relation `M=(m_0)/sqrt(1-v^2/C^2)`
