  1. ​In a particular system, the unit 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 equivalent to
    1. 0.1 N
    2. 1 N
    3. 10 N
    4. ​100 N
Correct Option: A

[F] = MLT – 2 = (10g) (10 cm) (0.1s) – 2
​= (10 – 2 kg) (10 – 1m) (10 – 1s) – 2 = 10 – 1 N.
