Question

The electric field at a distance $\frac{3R}{2}$ of the center of a charged conducting spherical shell of radius $R$ is $E$. The electric field at a distance $\frac{R}{2}$from the center of the sphere is

• A. $Zero$
• B. $E$
• C. $\frac{E}{2}$
• D. $\frac{E}{3}$

Answer 1

The correct option is A

$Zero$

Explanation for Correct answer:

Option A: $Zero$

1. Electric field: The physical field that surrounds electrically charged particles and exerts a force on all other charged particles in the field, either attracting or repelling them, is known as an electric field.
2. Here, $R$ is the radius of a spherical shell.
3. The electric field is $Zero$ inside the conducting charged spherical shell.
4. As a result, the electric field at $\frac{R}{2}$ from the sphere's center will be zero.
5. Hence, Option A is correct.

Explanation for Incorrect answer(s):

Option B: $E$ ;

Option C: $\frac{E}{2}$;

Option D: $\frac{E}{3}$

1. Since the electric field is $Zero$ inside the conducting charged spherical shell, then option B, option C, and option D are not valid.
2. Hence, option B, option C, and option D are not the correct answers.

Thus, option A is the correct answer.
