Consider a coil composed from a ferrite core and a wire winding. The mass of the
core is \(2\, \mathrm{kg}\).
The material for the wire is such that the mass of the wire of the length
\(30\, \mathrm{m}\) is bigger than the mass
of the wire of the length \(10\, \mathrm{m}\)
together with the ferrite core. In the following list identify a possible mass of one
meter of the wire.
\(110\, \mathrm{g}\)
\(100\, \mathrm{g}\)
\(0.01\, \mathrm{kg}\)
\(0.09\, \mathrm{kg}\)
