Two Concentric Imaginary Spherical Surfaces of Radius R and 2R $\phi$

question 131

Multiple Choice

Two concentric imaginary spherical surfaces of radius R and 2R respectively surround a positive point charge Q located at the center of the surfaces.When compared to the electric flux $\phi$ ₁ through the surface of radius R,the electric flux $\phi$ ₂ through the surface of radius 2R is

• A) \(\Phi _ { 2 } = \frac { 1 } { 4 } \Phi _ { 1 }\) .
• B) \(\Phi _ { 2 } = \frac { 1 } { 2 } \Phi _ { 1 }\) .
• C)\(\phi\) ₂ = \(\phi\) ₁.
• D)\(\phi\) ₂ = 2\(\phi\) ₁.
• E)\(\phi\) ₂ = 4\(\phi\) ₁.
