A coil is placed perpendicular to a magnetic field of $5000 \, \text{T}$ . When the field is changed to $3000 \, \text{T}$ in $2 \, \text{s}$ , an induced emf of $22 \, \text{V}$ is produced in the coil. If the diameter of the coil is $0.02 \, \text{m}$ , then the number of turns in the coil is:

A
$7$
B
$70$
C
$35$
D
$140$
