Application +4 | -1

A boat is moving due east in a region where the earth’s magnetic field is

5.0 \times {10^{ - 5}}\,\,\mathrm{N}{\mathrm{A}^{ - 1}}{\mathrm{m}^{ - 1}}

due north and horizontal. The boat carries a vertical aerial

1{\mkern 1mu} \mathrm{2}\,\mathrm{m}

long. If the speed of the boat is

\mathrm{1}\mathrm{.50}\,\,\mathrm{m}{\mathrm{s}^{ - 1}}

, the magnitude of the induced emf in the wire of aerial is

View answer and explanation

Correct option: C

\mathrm{0}.\mathrm{15}\,\,\mathrm{mV}

Option C (

\mathrm{0}.\mathrm{15}\,\mathrm{mV}

) is correct because it uses the formula for induced emf in a moving conductor in a magnetic field.
