A) \[\frac{x}{a}+\frac{y}{b}=\frac{1}{2}\]
B) \[\frac{x}{b}-\frac{y}{a}=2\]
C) \[ax+by=2\]
D) \[\frac{{{a}^{2}}}{{{x}^{2}}}+\frac{{{b}^{2}}}{{{y}^{2}}}=1\]
Correct Answer: C
Solution :
Magnetic field due to one side of the square at centre O. \[1.01\times {{10}^{5}}\]\[{{k}_{a}}\]\[\lambda \] Hence, magnetic field at centre due to all sides\[{{k}_{a}},\]You need to login to perform this action.
