Question

$1kg{m}^2/s^2=.............gc{m}^2/s^2$

• A. ${10}^6$
• B. ${10}^7$
• C. ${10}^8$
• D. ${10}^2$

Answer 1

The correct option is B ${10}^7$

We know that,

$1kg={10}^{3}g$

$1m^2={10}^{4}c{m}^2$

So, $1kg{m}^2{s}^{-2}=1kg\times 1m^2\times 1s^{-2}$

$={10}^{3}g\times {10}^{4}c{m}^2\times 1s^{-2}={10}^{7}gc{m}^2{s}^{-2}$

$\therefore 1kg{m}^2{s}^{-2}={10}^{7}gc{m}^2{s}^{-2}$
