A torsion balance has a sensitivity requirement (SR) of 6.0 mg. What is the MWQ of this balance if the maximum error permitted i
n using it is 4.2%? [round answer to a whole number]
1 answer:
Answer:
MWQ is 143 mg
Step-by-step explanation:
given data
sensitivity requirement (SR) = 6.0 mg
maximum error = 4.2%
to find out
MWQ
solution
we know here MWQ formula that is
MWQ =
................1
so here error is 4.2 % = 0.042
put here all these value in equation 1 we get
MWQ = 
MWQ = 
MWQ = 142.857 mg
so MWQ is 143 mg
