torque wrench length

Another physics problem....?
A. Calculate the torque produced by a 50-N perpendicular force at the end of a 0.2-m long wrench.
B. Calculate the torque produced by the same 50-N force when a pipe extends the length of the wrench to 0.5m.
The formula used to calculate torque is as follows:
T=torque
D=distance
F=force
T=FxD, or T=FD, or T=F(D), or Torque equals force times distance.
Answers:
A. 10 N/m torque
B. 25 N/m torque
