358344 Assertion :
Gauss's law can't be used to calculate electric field near an electric dipole.
Reason :
Electric dipole does not have symmetrical field.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.

358345 Read the Assertion and Reason carefully to mark the correct options given below:
Assertion :
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 :
Electric dipole consists of two equal and opposite charges.

1 Assertion is incorrect but Reason is correct.
2 Assertion is correct but Reason is incorrect.
3 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
