Final answer:
The torque produced by a 65 N force at the end of a 0.20 m wrench is calculated using the formula Torque = Force x Distance, which results in a torque of 13 Nm, corresponding to option D.
Step-by-step explanation:
To calculate the torque produced by a perpendicular force at the end of a wrench, you can use the formula Torque = Force x Distance.
In this specific question, the force applied is 65 N and the distance (length of wrench) is 0.20 m. So, the torque would be calculated by multiplying these two values.
Applying the formula:
Torque = 65 N x 0.20 m = 13 Nm.
Therefore, the correct option is D. 13 Nm, and it is the torque produced by this force at the end of the wrench.
