Question

Electric-field magnitude 'E' at points inside and outside a positively charged spherical conductor having charge Q and a radius R are ______.

विकल्प

• `1/(4piepsilon_0) "Q"/"R"^2, 1/(4piepsilon_0) "Q"/"R"^2`

• less than 0, `1/(4piepsilon_0) "Q"/"R"^2`

• 0, `1/(4piepsilon_0) "Q"/"R"`

• greater than 0, `1/(4piepsilon_0) "Q"/"R"^2`

Answer 1

Electric-field magnitude 'E' at points inside and outside a positively charged spherical conductor having charge Q and a radius R are less than 0, `underline(1/(4piepsilon_0) "Q"/"R"^2)`.

Explanation:

Because charge always resides on the surface of a conductor, the conductor field will be zero inside. Outside, the sphere field will behave similarly to that of a point charge.
