Question
A resistor connects two parallel conducting rails a distance $d$ apart. A conducting bar rolls along the rails at a constant velocity $v$ through a uniform magnetic field of $2.0 \mathrm{~T}$ perpendicular to the rails as shown.
The voltage $V$ across the resistor is measured.
The graph shows the variation of $V$ with $d$.
What is $V$ ?
A. $0.33 \mathrm{~m} \mathrm{~s}^{-1}$
B. $3.0 \mathrm{~m} \mathrm{~s}^{-1}$
C. $6.0 \mathrm{~m} \mathrm{~s}^{-1}$
D. $12.0 \mathrm{~m} \mathrm{~s}^{-1}$
