When the measured value of mass M becomes 2 M, the error in the measurement will be 0.00995 kg.
The percentage error is determined from the ratio of the error in meaurement to actual measurement.
Percentage error = (error / measurement) x 100%
Percentage error = (0.005 / 0.743) x 100%
Percentage error = 0.67%
New mass = 2 x 0.743
New mass = 1.486 kg
0.67 = (new error / 1.486) x 100%
0.0067 = new error / 1.486
new error = 0.0067 x 1.486
new error = 0.00995 kg
Thus, when the measured value of mass M becomes 2 M, the error in the measurement will be 0.00995 kg.
