The force F = i + 3j + 2k acts at the point (1, 1, 1).(a) Find the torque of the force about the point (2, −1, 5). Careful! The vector r goes from (2, −1, 5) to (1, 1, 1).(b) Find the torque of the force about the line r = 2i − j + 5k + (i − j + 2k)t. Note that the line goes through the point (2, −1, 5).
