In this experiment, you will determine the density of the material of a length of wire.

You are provided with

  • a length of wire,
  • a metre rule,
  • a 30 cm ruler,
  • four pieces of adhesive tape,
  • a wooden rod.
(a)

Using two pieces of adhesive tape, stick the wire to the bench and ensure that it is straight. Measure the length LL of the wire.

LL = ______

1M
(b)

Carefully wind the wire around the wooden rod, ensuring that the turns of wire are as close as possible. This is shown in Fig. 1.1. You may use adhesive tape to fix the ends of the wire to prevent the turns unwinding.

(i) Count the number NN of turns of wire on the rod.

NN = ______

(ii) Measure the length xx of the coil as shown in Fig. 1.1.

xx = ______

(iii) Calculate the diameter dd of the wire using d=xNd = \frac{x}{N}.

dd = ______

2M
(c)

Remove the coil of wire from the rod.

(i) Using the top-pan balance, measure the mass mm of the coil of wire.

mm = ______

(ii) Calculate the density ρ\rho of the material of the wire using the equation

ρ=4mπd2L\rho = \frac{4m}{\pi d^2 L}

ρ\rho = ______

2M
