Q In an experiment to determine the inertial mass of an object using Newton's second law , following graph is obtained between net force on the object and the acceleration produced in it. The mass of the object within error limits is:
1 .   1 . 0   k g 2 .   1   k g 3 .   1 . 0 ± 0 . 1 k g 4 .   1 . 0   ± 0 . 2 k g                                    

Dear student

F=mam=Fa=1.01.0=1.0 kgMaximum error in the measurement of force =length of one division=0.1 NMaximum error in the measurement of acceleration =length of one division=0.1 m/s2Fractional error in the measurement of the mass ismm=±FF+aamm=±0.11+0.11=±0.2m=±m×(0.2)m=±1.0×(0.2)=±0.2 kgm=(1.0±0.2)kgRegards
