A metallic sphere is placed in a uniform electric field. The lines of force follow the path (s) shown in the figure as
A
1
B
2
C
3
D
4
Answer
4
Explanation
Solution
The field is zero inside a conductor and hence lines of force cannot exist inside it. Also, due to induced charges on its surface the field is distorted close to its surface and a line of force must deviate near the surface outside the sphere.
