(c) If magnetic monopoles existed, how would the Gauss's law of magnetism be modified ?

Explanation

(c) If magnetic monopoles would have existed then Gauss.s law for magnetism could have been written as `oint overset(to) (B) . overset(to) (d) a = mu_(0) (sum_(q_(m) ) )`
(Where `sum_(q_m) =` net pole strength, enclosed by considered Gaussian surface)
(Note : Above law is analogous to Gauss.s law `oint overset(to) (E) . overset(to) (d) a = (sum_(q) ) /( in_0)` for electrostatics)
