The horizontal component of the earth's magnetic field at a place is \( 3 \times 10^{-4} \mathrm{~T} \) and the dip is \( \tan ^{-1}(4 / 3) \). A metal rod of length \( 0.25 \mathrm{~m} \) placed in the north-south position is moved at a constant speed of
\( \mathrm{P} \) \( 10 \mathrm{~cm} / \mathrm{s} \) towards the east. Find the e.m.f. induced in the rod.
