Answer question on the basis of your understanding of the following paragraph and the related studied concepts.
Eletric field around a single charges or a charges configuration can be pictorially mapped by drawing electric field lines in space. An electric field line is, in general, a curve drawn in such a way that the tangent to it at each point is in the direction of the net. field point. An arrow on the curve is obviously necessary to specify the direction of electric field from the two possible directions indicated by a tangent to the curve. A field line is a space curve i.e., a curve in three dimensions.
Electric field lines may be taken to be continous curve without any breaks. Relative density (i.e. closeness) of the field lines at different points indicate the relative strength of electric field at those points. The field lines crowd where the field is strong and are spaced apart where it is weak.
A solid metallic sphere is placed in a uniform electric field. The electric field lines around the sphere follow the path(s) shown in the figure as:

Options

A. 1
B. 2
C. 3
D. 4

Answer

d

Explanation

[ No field exists inside a metal sphere hence no field lines are possible inside the sphere. Uniform field means that the field sphere hence no field lines are possible inside the sphere. Uniform field means that the field lines must be parallel straight lines but near the metallic sphere they bend and end/start normally at/ from the surface of sphere.]
