  1. 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 equivalent to
    1. 0.1 N
    2. 1 N
    3. 10 N
    4. 100 N
Correct Option: A


n2 = n1
M1
L1
T1
-2

= 10
Thus if the new unit of force is
10 X = 1 N or X = 0.1
