Magnetic field due to a current carrying conductor at an outside point is given by B=(μ0 1/2 π r) T

Q. The magnetic field at point $P$ of given figure due to carrying of current I by a conductor of radius $R$ , is

$\frac{μ _{0} I}{4 π r}$

$\frac{μ _{0} I}{2 π r}$

$\frac{μ _{0} I}{2 π R}$

$\frac{μ _{0} I}{4 π R}$

Magnetic field due to a current carrying conductor at an outside point is given by $B = \frac{μ _{0} 1}{2 π r} T$
