A wheel of radius R and mass M is placed at the bottom of a fixed step of height R as shown in the figure. A constant force is continuously applied on the surface of the wheel so that it just climbs the step without slipping. Consider the torque about an axis normal to the plane of the paper passing through the point Q. Which of the following options is/are correct ?
     
  • a)
     If the force is applied normal to the circumference at point X then is constant
  • b)
    If the force is applied tangentially at point S then but the wheel never climbs the step
  • c)
    If the force is applied normal to the circumference at point P then is zero
  • d)
    If the force is applied at point P tangentially then decreases continuously as the wheel climbs
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
A wheel of radius R and mass M is placed at the bottom of a fixed step...
(A) is incorrect.
If force is applied normal to surface at point X
τ = Fy R sinθ
Thus τ depends on θ & it is not constant
(B) is incorrect
if force applied tangentially at S

but it will climb as mentioned in question.
If force is applied normal to surface at P then line of action of force will pass from Q & thus τ = 0
(D) is incorrect.
if force is applied at P tangentially the
 Constant

This question is of jee advanced 2017
answer given by jee was d option .
the point that should be noticed here is that force applied at p is always vertical ,tangential only at the given instant

its option b is also correct but not given by jee
