Question

An uncharged sphere of metal is placed in between charged plates as shown. The lines of force look like(a) A(b) B(c) C(d) D

Answer 1

Answer:

Image A

Explanation:

An important property of electric field is that the field line never intersects each other.  The electric lines of force never intersect the conductor as well. They are perpendicular and slightly curved near the surface of the conductor.

Polarization will take place in sphere so that the net electric field inside the metal is zero. We need to ensure that the electric lines of forces are always perpendicular to metal surface and that there are no lines of force inside the metal. The closest figure depicting these characteristics is image A.
