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 is equivalent to:

G1 Physics · Accepted Answer

Step 1: One force unit = (10 g)(10 cm)/(0.1 s)² = (10⁻² kg)(10⁻¹ m)(10⁻¹ s)⁻² = 10⁻¹ N = 0.1 N. Final: Hence option A.
