A) \[0.654\text{ }T\]
B) \[0.336\text{ }T\]
C) \[1.576\text{ }T\]
D) \[0.939\text{ }T\]
Correct Answer: B
Solution :
Here weight of the wire is balanced by the extene magnetic force. So, \[Bil=mg\] \[B=\frac{mg}{il}\] \[=\frac{300\times {{10}^{-3}}\times 10}{35\times 2.5}=0.34\,T\]You need to login to perform this action.
