Question

The force, F vector =(2i + 3j - 4k) N and position vector, r vector = (-2i - 3j +4k) m arerepresented on a body in rotational motion. Find out the magnitude of torque acting on the body.

Answer 1

F=(2i+3j-4k) and r=(-2i-3j+4k) we know that Torque =F×r for cross multiplication of two vectors we use determine method then we found that Torque is zero.
