Question

A cone of base radius R and height h is located in a uniform electric field E parallel to its base. The electric flux entering the cone is : (A) (1/2) E h R (B) E h R (C) 2 E h R (D) 4 E h R

Tardigrade Admin · Accepted Answer

flux φ = E⋅ A⊥ = E((1/2)h×2R) = Ehr

Q. A cone of base radius R and height h is located in a uniform electric field $E$ parallel to its base. The electric flux entering the cone is :

$\frac{1}{2}$ E h R

E h R

2 E h R

4 E h R

flux $ϕ = E \cdot A_{⊥}$
$= E (\frac{1}{2} h \times 2 R)$
$= E h r$
