In an experiment, mass of an object is measured by applying a known force on it, and then measuring its acceleration. IF, in the experiment, the measured values of applied force and the measured acceleration are F=10.0 0.2 N and a=1.00 0.01 m / s ² , respectively, the mass of the object is
Options
- A10.0 Kg
- B10.0 0.1 Kg
- C10.0 0.3 Kg
- D10.0 0.4 Kg
Correct answer
C. 10.0 0.3 Kg
Step-by-step solution
F = Ma M = f a M 100 M = f f 100+ a a 100 = 0.2 10 + 0.01 1 M =0.03 10 M =10 0.3 ~kg
