JEE Mains · Physics · STD 12 - 1. Electric charges and fields
Given below are two statement: one is labelled as Assertion \(A\) and the other is labelled as Reason \(R\). Assertion \(A:\) If an electric dipole of dipole moment \(30 \times 10^{-5}\,Cm\) is enclosed by a closed surface, the net flux coming out of the surface will be zero. Reason \(R\) : Electric dipole consists of two equal and opposite charges. In the light of above, statements, choose the correct answer from the options given below:
- A Both \(A\) and \(R\) are true and \(R\) is the correct explanation of \(A\)
- B \(A\) is true but \(R\) is false
- C Both \(A\) and \(R\) true but \(R\) is NOT the correct explanation of \(A\)
- D \(A\) is false but \(R\) is true
Answer & Solution
Correct Answer
(A) Both \(A\) and \(R\) are true and \(R\) is the correct explanation of \(A\)
Step-by-step Solution
Detailed explanation
\(\overrightarrow{ P }=30 \times 10^{-5}\,Cm\) Using Gauss law \(\phi=\frac{Q_{\text {in }}}{\varepsilon_0} \text { and } Q_{\text {in }}=0\) \(\Rightarrow \phi=0\) Statement \(1\) and Statement \(2\) are correct.
