A) \[\frac{B(\pi ab)}{R}\]
B) \[\frac{B(\pi ab-\pi {{r}^{2}})}{R}\]
C) \[\frac{B\pi {{r}^{2}}}{R}\]
D) \[\frac{B\pi br}{R}\]
Correct Answer: B
Solution :
\[\Delta Q\,\,=\,\frac{\Delta \phi }{R}\,\,=\,\frac{{{\phi }_{f}}-{{\phi }_{i}}}{R}\,\,=\,\,\frac{B(\pi ab-\pi {{r}^{2}})}{R}\]You need to login to perform this action.
