A) \[B=\frac{{{\mu }_{0}}}{4\pi }\frac{i}{a}\,(sin\,{{\theta }_{1}}+sin\,{{\theta }_{2}})\]
B) \[B=\frac{{{\mu }_{0}}}{4\pi }\frac{i}{a}\,(sin\,{{\phi }_{1}}+sin\,{{\phi }_{2}})\]
C) Both of [a] and [b]
D) None of these
Correct Answer: B
Solution :
From the given figure, magnetic field at point O is given by s \[B=\frac{{{\mu }_{0}}}{4\pi }\,\frac{i}{a}\,\,(sin\,\,{{\phi }_{1}}+sin{{\phi }_{2}})\]You need to login to perform this action.
