magnetic field B about an axis perpendicular to the
length of rod passing through point 'O' as shown
in the figure. The potential difference between the
points P and Q, Vp - Vois​

Answer 1

Answer:

Induced EMF

Explanation:

E = 1 / 2 × B [ x²2 - x²1 ] × w

= 1 / 2 × B × W × [ ( 2L )² - ( L )² ]

E = 3 / 2 B W L²

Option A is the answer
