Question

28.
A solid metallic sphere is placed in a uniform electric field. Which of the lines A, B, C and D shows the correct path and why?​

Answer 1

Answer:

D.

Explanation:

Electric lines of force are always perpendicular to conductor surfaces.

Answer 2

EXPLANATION

GIVEN

A solid metallic sphere is placed in a

uniform electric field.

TO FIND

which of these lines A, B, C, D shows the

correct path and why?

SOLUTION

Electric field inside the conductor is zero

Also, since the conductor is in equipotential

region. the electric field lines enter into or

came out from the conductor is at an angle

of 90°.

Hence, path (D) is follow electric field lines

REASON

There are no electric field lines within a

metallic sphere and field lines are normal at

each of the surface.
