A heavy particle of mass m falls freely near the earth’s surface. What is the torque acting on this particle about a point 50 cm east to the line of motion? Does this torque produce any angular acceleration in the particle?

Torque on the body in vector form is



Hence



in the direction of



As falling motion is close to earth, the force could simply be written as F=mg



Putting values, Nm


=5Nm (in the direction of)


No, there won’t be any visible angular acceleration.
