Question
Prove that $1 N=10^5$ dyne. Is $1\ N$ same as $1 kgms ^{-2}$ ?
✓
Answer
$1$ newton $=1 kg \times 1 ms^{-1}=1000 g \times 100 cms ^{-1}=105 cms ^{-1}$.
$1$ dyne $1 g \times 1 cms ^{-1}=1 cms ^{-1}$.
So $1$ newton $=10^5$ dyne.
$1$ dyne $1 g \times 1 cms ^{-1}=1 cms ^{-1}$.
So $1$ newton $=10^5$ dyne.
