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,b,d
D. b,a,d,c

Answer

D

Explanation

`B = (mu_0i)/(2pir)`
