If 1gm cms–1 = x Ns, then number x is equivalent to

A

1×10−11 \times 10^{- 1}

B

3×10−23 \times 10^{- 2}

C

6×10−46 \times 10^{- 4}

D

1×10−51 \times 10^{- 5}

Answer

1×10−51 \times 10^{- 5}

Explanation

Solution

gm−cms−1gm - cms^{- 1} =10−3kg×10−2m×s−1= 10^{- 3}kg \times 10^{- 2}m \times s^{- 1}

=10−5kg×m×s−1= 10^{- 5}kg \times m \times s^{- 1}

= 10–5 Ns
