The force \[{{10}^{-3}}\ operatorname{N}\],is equivalent to:

A) 100 mg

B) 100 g

C) 10 g

D) 10 mg

Correct Answer: A

Solution :

Option [a] is correct.

Explanation: \[{{10}^{-3}}\operatorname{N}\]= mass in \[\operatorname{kg} \times g\]in\[\operatorname{m}/{{s}^{2}}\]

Or, \[{{10}^{-3}}\operatorname{N}\]= mass \[\times \] 10

\[\therefore \ Mass=1{{0}^{-4}}kg=100mg\]
