Physics: A potential difference of 35 mV is developed across the ends of a 12.0-cm-long wire as it moves through a 0.27 T uniform magnetic field at a speed of 6.0 m/s. The magnetic field is perpendicular to the axis of the wire. What is the angle between the magnetic field and the wire s velocity?

Angle between magnetic field and wire velocity is $10.372^{\circ}$

Explanation:

We have given potential difference e = 35 mV = 0.035 volt

Length of the wire l = 12 cm = 0.12 m

Velocity v = 6 m/sec

Magnetic field B = 0.27 T

It is known that potential difference developed

$e=Bvlsin\Theta$

$0.035=0.27\times 6\times 0.12\times sin\Theta$

$sin\Theta =0.18$

$\Theta =10.372^{\circ}$

So angle between magnetic field and wire velocity is $10.372^{\circ}$

simplifying this expression (√8^4 × √6^4)^3/2 = 110592

so 2^12 ×3^3= 110592

similar 2^9 ×6^3 =110592
