A) \[\frac{B}{2}\]
B) \[y=A\sin (Bx+Ct+D)\]
C) \[[{{m}^{0}}{{L}^{-1}}{{T}^{0}}]\]
D) B
Correct Answer: B
Solution :
For a long straight wire, the magnetic field. \[\frac{1}{3}M{{L}^{2}}\] when, r = 5cm \[\frac{3}{2}M{{L}^{2}}\] ?.... (i) Similarly, when r = 20 cm \[\frac{3}{4}M{{L}^{2}}\] From Eqs. (i) and (ii), we get \[M{{L}^{2}}\]You need to login to perform this action.
