If the stress on a wire is 10\(^{7}\)NM\(^{-2}\) and the wire is stretched from its original length of 10.00m to 10.05m. The young's modulus of the wire is?
a
5.0 x 10\(^{-4}\)Nm\(^{-2}\)
b
5.0 x 10\(^{-5}\)Nm\(^{-2}\)
c
2.0 x 10\(^{-8}\)Nm\(^{-2}\)
d
2.0 x 10\(^{9}\)Nm\(^{-2}\)

Y = stress/strain, given stress = 10^7
and Strain = e/l
Y = (10^7 x 10)/0.05 = 2 x 10^9 Nm-²

the answer should be option c
please my school review it again
200,000,000 is approximately to 2.0×10^-8
