1. Electric Charges and Fields
hard

एकसमान पृष्ठीय आवेश घनत्व $\sigma_{+}$व $\sigma_{-}$वाली दो आवेशित पतली अनन्त लम्बी समतलीय शीटों पर विचार कीजिये जहाँ $\left|\sigma_{+}\right|>\left|\sigma_{-}\right|$है, तथा ये आपस में समकोण पर प्रतिच्छेदित करती है। इस निकाय के लिये विधुत क्षेत्र रेखाओं का सर्वाधिक सही चित्रण होगा:-

A
B
C
D
(JEE MAIN-2020)

Solution

Thin infinite uniformly charged planes produces uniform electric field therefore option $2$ and option $3$ are obviously wrong.

And as positive charge density is bigger in magnitude so its field along $Y$ direction will be bigger than field of negative charge in $X$ direction and this is evident in option $1$ so it is correct.
