A thin straight vertical conductor has `10amp` current flows vertically upwards. It is present at a place where `B_(H)=4xx10^(-6)T`. Arrange the net magnetic induction at the following points in ascending order
`a)` at `0.5m` on south of conductor
`b)` at `0.5m` on west of conductor
`c)` at `0.5m` on east of conductor
`d)` at `0.5m` on north`-` east of conductor

Options

A. `a,b,c,d`
B. `a,b,d,c`
C. `a,c,d,b`
D. `b,a,d,c`

Answer

D

Explanation

`B=(mu_(0)i)/(2pir)`
