Correct Option - 1

Detailed Solution:

Direction of E in the direction of y axes so flux is only due to top and bottom surface for bottom surface y = 0 E = 0

and for top surface y = 0.5 m So

$E = 150 \times {(0.5)}^{2} = \frac{150}{4}$

$f l u x f l o w i n g ? = E A = \frac{150}{4} \times {(0.5)}^{2}$

$= \frac{150}{16}$

Gausses law $? = \frac{q}{ε_{0}}$

$\frac{150}{16} = \frac{q}{ε_{0}}$

$= 8.3 \times 1 0^{- 11} C$

Direction of E in the direction of y axes so flux is only due to top and bottom surface for bottom surface y = 0 E = 0and for top surface y = 0.5 m      So <math> <mrow> <mi>E</mi> <mo>=</mo> <mn>1</mn> <mn>5</mn> <mn>0</mn> <mo>×</mo> <msup> <mrow> <mrow> <mo> (</mo> <mrow> <mn>0</mn> <mo>.</mo> <mn>5</mn> </mrow> <mo>)</mo> </mrow> </mrow> <mrow> <mn>2</mn> </mrow> </msup> <mo>=</mo> <mfrac> <mrow> <mn>1</mn> <mn>5</mn> <mn>0</mn> </mrow> <mrow> <mn>4</mn> </mrow> </mfrac> </mrow> </math> <math> <mrow> <mi>f</mi> <mi>l</mi> <mi>u</mi> <mi>x</mi> <mtext> </mtext> <mtext> </mtext> <mi>f</mi> <mi>l</mi> <mi>o</mi> <mi>w</mi> <mi>i</mi> <mi>n</mi> <mi>g</mi> <mtext> </mtext> <mtext> </mtext> <mi>? </mi> <mo>=</mo> <mi>E</mi> <mi>A</mi> <mo>=</mo> <mfrac> <mrow> <mn>1</mn> <mn>5</mn> <mn>0</mn> </mrow> <mrow> <mn>4</mn> </mrow> </mfrac> <mo>×</mo> <msup> <mrow> <mrow> <mo> (</mo> <mrow> <mn>0</mn> <mo>.</mo> <mn>5</mn> </mrow> <mo>)</mo> </mrow> </mrow> <mrow> <mn>2</mn> </mrow> </msup> </mrow> </math>              <!- [if gte mso 9]-> <!- [endif]-> <math> <mrow> <mo>=</mo> <mfrac> <mrow> <mn>1</mn> <mn>5</mn> <mn>0</mn> </mrow> <mrow> <mn>1</mn> <mn>6</mn> </mrow> </mfrac> </mrow> </math>             <!- [if gte mso 9]-> <!- [endif]->Gausses law <math><mrow><mi>? </mi><mo>=</mo><mfrac><mrow><mi>q</mi></mrow><mrow><msub><mrow><mi>ε</mi></mrow><mrow><mn>0</mn></mrow></msub></mrow></mfrac></mrow></math>    <math> <mrow> <mfrac> <mrow> <mn>1</mn> <mn>5</mn> <mn>0</mn> </mrow> <mrow> <mn>1</mn> <mn>6</mn> </mrow> </mfrac> <mo>=</mo> <mfrac> <mrow> <mi>q</mi> </mrow> <mrow> <msub> <mrow> <mi>ε</mi> </mrow> <mrow> <mn>0</mn> </mrow> </msub> </mrow> </mfrac> </mrow> </math>            <!- [if gte mso 9]-> <!- [endif]-> <math> <mrow> <mo>=</mo> <mn>8</mn> <mo>.</mo> <mn>3</mn> <mo>×</mo> <mn>1</mn> <msup> <mrow> <mn>0</mn> </mrow> <mrow> <mo>−</mo> <mn>1</mn> <mn>1</mn> </mrow> </msup> <mi>C</mi> </mrow> </math>              <!- [if gte mso 9]-> <!- [endif]->
