11. A parallel plate capacitor having square plate of area \( a \) and separation between plates \( d \) is completely filled with \( a \) dielectric of dielectric constant \( k \). Capacitor is connected with a battery of potential difference \( V \). Now dielectric is pulled with constant speed \( u \). Find the initial value of current.
(A) \( \frac{\varepsilon_{0} \sqrt{a u}}{2 d}(k-1) V \)
(B) \( \frac{\varepsilon_{0} \sqrt{a u}}{d}(k-1) V \)
(C) Zero
(D) \( \frac{2 \varepsilon_{0} \sqrt{a} u}{d}(k-1) V \)
