A metallic cube of side 15   cm moving along y -axis at a uniform velocity of 2   m   s - 1 . In a region of uniform magnetic field of magnitude 0 . 5   T 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 .

Correct answer

150

Step-by-step solution

Using the equation q E = q v B   ⇒ E = v B Using the relation ∆ V = E d ⇒ ∆ V = v B d = 2 × 1 2 × 0 . 15   V = 0 . 15   V = 150   mV
