Moving Charges and Magnetism

Question: A solenoid is $1.0$ metre long and it has $4250$ turns. If a current of $5.0$ ampere is flowing through it, what is the magnetic field at its centre$[{\mu _0} = 4\pi \times {10^{ - 7}}\,weber/amp - m]$

1) $5.4 \times {10^{ - 2}}\,weber/{m^2}$

2) $2.7 \times {10^{ - 2}}\,weber/{m^2}$

3) $1.35 \times {10^{ - 2}}\,weber/{m^2}$

4) $0.675 \times {10^{ - 2}}\,weber/{m^2}$
