Answer:
Answer is option D)
Normal will not produce torque
Explanation:
Refer the image for diagram
You can see :
Frictional force is balanced by mg
And force applied is balanced by N (normal)
Torque due to F = 0
As it passes through centre of the body
Therefore Normal will not produce any torque !!
Thus option D is incorrect and it's ur answer
