JEE Mains · Physics · STD 12 - 1. Electric charges and fields

एक घन \(\overrightarrow{ E }=150 y ^{2} \hat{ j }\) के विधुत क्षेत्र में रखा है। घन की भुजा \(0.5\, m\) है तथा यह क्षेत्र में चित्रानुसार रखा है। घन के अन्दर आवेश \(.....\times 10^{-11} {C}\) है।

  1. A \(3.8\)
  2. B \(8.3\)
  3. C \(0.38\)
  4. D \(830\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(8.3\)

Step-by-step Solution

Detailed explanation

As electric field is in \(y-\)direction so electric flux is only due to top and bottom surface Bottom surface \({y}=0\) \(\Rightarrow {E}=0 \Rightarrow \phi=0\) Top surface \({y}=0.5\, {m}\) \(\Rightarrow {E}=150(0.5)^{2}=\frac{150}{4}\) Now flux…
