Question

In a particular system, the units of length, mass and time are chosen to be 10 cm, 10 g and 0.1 s respectively. The unit of force in this system will be-

• A. 0.1 N
• B. 1 N
• C. 10 N
• D. 100 N

Answer 1

Answer: (A)

0.1 N

Answer 2

1 N = n₂ unit

n₂ = 1 $\left\lbrack \frac{1kg}{10g} \right\rbrack^{1}$ $\left\lbrack \frac{1m}{10cm} \right\rbrack^{1}$ $\left\lbrack \frac{1s}{0.1s} \right\rbrack^{- 2}$
