The torque on the particle about the origin is
The formula for calculating the torque is expressed as:
F is the force applied
r is the radius of the particle;
Given the following parameters
Substitute the given parameter into the formula:
According to cross product,
Taking the cross product of the force and the radius is

Torque,
Explanation:
It is given that,
Force acting on the particle,
Position of the particle,
We need to find the torque on the particle about the origin. It is equal to the cross product of position and the force. Its formula is given by :
The cross product of vectors is given by :
or
So, the torque on the particle about the origin . Hence, this is the required solution.
