Given that.
Force acting on the particle,
Position of the particle,
To find,
(a) Torque on the particle about the origin.
(b) The angle between the directions of r and F
Solution,
(a) Torque acting on the particle is a scalar quantity. It is given by the cross product of force and position. It is given by :
So, the torque on the particle about the origin is (32 N-m).
(b) Magnitude of r,
Magnitude of F,
Using dot product formula,
Therefore, this is the required solution.
