The electric field in a region is radially outward with magnitude 
. The charge contained in a sphere of radius 
centered at the origin is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Flux linked with the given sphere 
where Q = Charge enclosed by the sphere.
Hence Q = φ φ ε ε o = (EA) ε ε o
⇒ ⇒ Q = 4 π π ( γ γ o ) 2 × × A γ γ o ε ε o = 4 π π ε ε o A γ γ o 3 .
