5.

A ladder is resting on a rough ground and leaning against a smooth vertical wall. The force of friction will act

 [A]. downward at its upper end [B]. upward at its upper end [C]. zero at its upper end [D]. perpendicular to the wall at its upper end

Explanation:

No answer description available for this question.

 Lucky said: (Jun 17, 2013) Friction will be always at slipping point of ladder means a horizontal surface. At wall there will be reaction Force Not Friction so.

 Haseen said: (May 22, 2014) Wall is smooth given in the question so no friction.

 Lalit Swami said: (May 8, 2015) Because the wall is smooth.

 Sumi said: (Jul 3, 2018) I think the correct answer is B.

 Uttu Don said: (Oct 2, 2018) Option B is correct.

 Ashish said: (Dec 23, 2018) There is no normal reaction at an upper end.

 Omid said: (Dec 7, 2019) Why B is correct. The upper end is smooth so no friction. The given answer is right.

 Mamdud said: (Apr 7, 2020) Friction can be less but not zero.

 Ravindra Vishwakarma said: (Aug 7, 2020) If any ladder is inclined against roughwall then friction act in both upward of vertical wall as well as towards it.
