A) 0.2 A
B) 0.4 A
C) 4 A
D) 40 A
Correct Answer: B
Solution :
Magnetic field at the centre of a circular loop carrying current I is given by \[\beta \] where r is radius of circular loop. \[[{{M}^{-1}}L{{T}^{-2}}A]\] \[[{{M}^{-2}}L{{T}^{-2}}{{A}^{-1}}]\] Given, \[[ML{{T}^{-2}}{{A}^{-2}}]\] \[[ML{{T}^{-1}}{{A}^{-1}}]\] \[{{\beta }^{-}}\]You need to login to perform this action.
