As shown in the figure two infinitely long, identical wires are bent by `90^(@)` and placed in such a way that the segments LP and QM are along the x-axis , while segments PS and QN are parallel to the Y-axis If OP=OQ=4 cm ,and the magnitude of the magnetic field at O is `10^(-4)` T, and the magnitude of the current in each wire and the direction of the magnetic field at O will be
`(mu _(o) =4pi xx10-7NA^(-2)):`

A

40A, perpendicular out of the page

B

40A , perpendicular into the page

C

20A , perpendicular out of the page

D

Text Solution

Verified by Experts

The correct Answer is:
D
`B=2((mu_0I)/(4pid))`
`10^(-4)=2(4pixx10^(-7)xxI)/(4pixx(4/100))`
`I = 20 A`
