Solution

The correct option is B $- \frac{2 σ}{ϵ_{0}}^k$
$⇀ E = - \frac{σ}{2 ϵ_{0}}^k - \frac{2 σ}{2 ϵ_{0}}^k = - \frac{2 σ}{ϵ_{0}}^k$

The correct option is B −2σϵ0^k⇀E=−σ2ϵ0^k−2σ2ϵ0^k=−2σϵ0^k

The correct option is B $- \frac{2 σ}{ϵ_{0}}^k$
$⇀ E = - \frac{σ}{2 ϵ_{0}}^k - \frac{2 σ}{2 ϵ_{0}}^k = - \frac{2 σ}{ϵ_{0}}^k$
