**Step-by-step explanation:**

**Answer:**

41.5 N

**Step-by-step explanation:**

Torque is given by:

τ = rF

Solved for force:

F = τ / r

The value of r is the distance from the end of the wrench to the center of the lid, which is:

r = (0.089m / 2) + 0.17m

= 0.2145m

Therefore:

F = 8.9N∙m / 0.2145m

**= 41.5N**
