For a rod pivoted at one end, a

15\,\text{N}

force acts perpendicular to the rod at a distance of

20\,\text{cm}

from the pivot. Answer the following: (a) By what factor will the torque change if the distance of application is doubled while the force remains unchanged? (b) By what factor will the torque change if the distance remains

20\,\text{cm}

but the force is halved?
