The question seems to be incomplete. However, I can guide you on how to solve such a problem if we had all the necessary information.

The formula to calculate the force (F) required to stretch a wire is given by:

F = (Y * A * ΔL) / L

Where:
Y = Young's modulus of the material (in this case, steel)
A = Cross-sectional area of the wire
ΔL = Change in length of the wire
L = Original length of the wire

From the question, we know that:
Y = 20 x 10^10 N/m^2 (Young's modulus of steel)
A = 1 cm^2 = 1 x 10^-4 m^2 (converted from cm^2 to m^2)
ΔL = L (since the wire is stretched to double its original length)

Substituting these values into the formula, we get:

F = (20 x 10^10 N/m^2 * 1 x 10^-4 m^2 * L) / L

Simplifying this, we find that the force required is 2 x 10^6 N.

However, without the original length of the wire (L), we cannot calculate the exact force required. Please provide the original length of the wire to get the exact answer.
