A new system of units is proposed in which unit of mass is

\alpha \mathrm{~kg}

, unit of length is

\beta \mathrm{~m}

and unit of time is

\gamma \mathrm{~s}

. What will be value of

5 \mathrm{~J}

in this new system:

View answer and explanation

Correct option: B

5 \alpha^{-1} \beta^{-2} \gamma^2

Option B (

5 \alpha^{-1} \beta^{-2} \gamma^2

) is correct because it correctly converts the units of energy from the SI system to the new system.
