Answers
Answer:
The correct answer of this question is Electric field is perpendicular to the surface of the sphere .
Explanation:
Given - A metallic solid sphere of radius R is given the charge Q.
To Find - Which of the following statement is true.
Electric field is perpendicular to the surface of the sphere is the true statement of a metallic solid sphere of radius R is given the charge Q.
In two dimensions, an equipotential surface is circular. The electric field lines are opposite the equipotential lines because they are oriented radially away from the charge. As a result, the electric field intersects the equipotential surface perpendicularly.

Answer:
The answer is
option (c) Electric field is perpendicular to the surface of the sphere
Explanation:
The fields of electricity are the reverse of the equipotential lines since they are oriented radially away from the charge. The electric potential surface and the electric field are therefore parallel.
An equipotential surface is circular in two dimensions. Due to the fact that they are pointed radially away from the charge, the electrical field lines are in opposition to the equipotential lines. The equipotential surface is thus parallel to the ground intersected by the electric field as a result.
In all cases, electric field lines are parallel to the equipotential surface. enlarge. In all cases, electric field lines are parallel to the equipotential surface.
All over on equipotential surfaces has the same potential. Equipotential surfaces are nearer together for stronger fields. At every point, these equipotential surfaces are always parallel to the direction of the electric field.
