A torque meter is calibrated to reference standards of mass, length and time each with 5% accuracy. After calibration, the measured torque with this torque meter will have net accuracy of:
Text Solution
Verified by ExpertsThe correct answer is:
B
Dimensional formula for Torque [ 
] = [ML 2 T 2 ]
Now
Percentage error in torque = % 
= % M + 2 % L
2 % T
% 
= 25%
