Question 19 NECO • 2017 • PHYSICS • objective

In the laboratory setup shown, a spring balance is used to weigh an unknown mass \(A\). The balance scale is calibrated in grams. When mass \(A\) is hung, the pointer indicates a reading of \(245\)\,g. (i) Convert this reading to newtons (use \(g=9.8\)\,m\,s⁻²). (ii) The true mass of \(A\) is \(0.250\)\,kg. Determine the percentage error in the balance reading.

A. 2.401 N, 2.0% high

B. 2.450 N, 2.0% low

C. 2.401 N, 1.5% low

Correct Answer D. 2.401 N, 2.0% low

Correct Answer

Correct Option:

2.401 N, 2.0% low
