Answer:

(a) Since the charge at any point inside sphere is zero.

Verified answer

Answer:

(a) At any point on the surface of the sphere, no electric field is produced. This is because the electric field produced by a point charge is inversely proportional to the square of the distance from the point charge. Since the radius of the sphere is 2m, the distance from any point on the surface of the sphere to the center of the sphere is 2m. Therefore, the electric field produced by the sphere at any point on the surface of the sphere is zero.

(b) At any point outside the sphere, no electric field is produced. This is because the electric field produced by a point charge is inversely proportional to the square of the distance from the point charge. Since the radius of the sphere is 2m, the distance from any point outside the sphere to the center of the sphere is greater than 2m. Therefore, the electric field produced by the sphere at any point outside the sphere is zero.

(c) At a distance of more than 2m from the center of the sphere, no electric field is produced. This is because the electric field produced by a point charge is inversely proportional to the square of the distance from the point charge. Since the distance from the point to the center of the sphere is greater than 2m, the electric field produced by the sphere at the point is zero.

(d) At a distance of more than 10m from the center of the sphere, no electric field is produced. This is because the electric field produced by a point charge is inversely proportional to the square of the distance from the point charge. Since the distance from the point to the center of the sphere is greater than 10m, the electric field produced by the sphere at the point is zero.

Hola! Morning! It's bin quite sometime, ig? Hru? :)

Hope this helps btw ^^// ✨✨
