A current `I` is flowing thorugh the loop. The direction of the current and the shpae of the loop are as the shown in the figure. The magnetic fild at the centre of the loop is `(mu_(0) I)/(R)` times
`(MA = R, MB = 2R, /_DMA = 90^(@))`

Options

A. `(5)/(16)(mu_(0)i)/(R )`, but out of the plane of the paper
B. `(5)/(16)(mu_(0)i)/(R )`, but into the plane of the paper
C. `(7)/(16)(mu_(o)i)/(R )`, but out of the plane of the paper
D. `(7)/(16)(mu_(o)i)/(R )`, but into the plane of the paper

Answer

D
