Question

A new system of units is defined as $1Dhoni=10newtons$, $1Z{A}^{\prime }K=10m/s$, $1\text{T'KAR}=10hertz$. If in this system unit of work is $Yuvi$, then $10Yuvi$ is equal to

Answer 1

Work done is given by,
$W=Fs$
$W=Fvt$

$1J=1N\times 1m/s\times 1s$

$1J=\frac{1}{10}Dhoni\times \frac{1}{10}Z{A}^{\prime }K\times 10(T^{\prime }KAR{)}^{-1}$

(as we know $hertz=s^{-1}$)

$1J=\frac{1}{10}Yuvi$

$\Rightarrow 1Yuvi=10J=10Yuvi=100J$

Final answer: $100J$
