Neco 2018 Mathematics Question 3
Practice objective / multiple choice question 3 from the 2018 Neco Mathematics examination.
The resistance \(R\) (in ohms) of a wire varies directly as its length \(L\) (in metres) and inversely as the square of its cross‑sectional area \(A\) (in \(\text{mm}^2\)). A wire of length \(2.0\) m and area \(1.0\) mm\(^2\) has resistance \(8\ \Omega\). What will be the resistance of a wire of length \(3.5\) m and area \(1.5\) mm\(^2\)?
