A square frame of wire abcd of side \( 1 \mathrm{~m} \) has a total resistance of \( 4 \Omega \). It is pulled out of a magnetic field \( B=1 \mathrm{~T} \) by applying a force of \( 1 \mathrm{~N} \) (figure). It is found that the frame moves with constant speed. Find (a) this constant speed, (b) the emf induced in the loop, (c) the potential difference between the points \( \mathrm{a} \) and \( \mathrm{b} \) and (d) the potential difference between the points \( \mathrm{c} \) and \( \mathrm{d} \).
