Assertion : Gauss's law of magnetism is different from that for electrostatics.
Reason Isolated magnetic poles are not known to exist.

Options

A. Both A and Rare Tuę and R is the correct explanation of A
B. Both A and R are true but R is NOT the correct explanation of A
C. A is true but R is false
D. A is false and R is true

Answer

A

Explanation

In electrostatics, Gauss.s law:
`= int vecE. vecdA = (q)/(epsi _(0))`
Gauss.s low of magnetism:
`int vecB. vecdA = 0`
Gauss.s law of magnetism is different from Gauss.s law of electrostatics. Hence, the assertion is true.
Electric charge may or may not exist in pair. But magnetic poles always exist m pair.
No magnetic monopole exists. This is the reason why . Gauss.s law of magnetism is different from Gauss.s law of electrostatics. So, the reason, is also true and explains the assertion
