A metallic cube of side

15cm

moving along

y

-axis at a uniform velocity of

2m{s}^{- 1}

. In a region of uniform magnetic field of magnitude

0 . 5T

directed along

z

- axis. In equilibrium the potential difference between the faces of higher and lower potential developed because of the motion through the field will be

mV

A metallic cube of side 15cm moving along y -axis at a uniform velocity of 2m s ^ - 1 . In a region of uniform magnetic

Correct answer

150

Step-by-step solution

Using the equation

$qE = qvB ⇒ E = vB$

Using the relation $∆ V = Ed$

$⇒ ∆ V = vBd$

$= 2 \times \dfrac{1}{2} \times 0 . 15V$
$= 0 . 15V = 150mV$
