A man pushes against a rigid, immovable wall while standing on rough ground. Which of the following statement(s) is/are wrong concerning this situation?

Options:(select one or more)

Answer:

ACD

Solution:

(B) is a correct statement: by Newton's third law the wall pushes back with exactly 200 N.

(A) is wrong: with $μ > 1$ , friction can exceed mg, so the push can exceed his weight.

(C) is wrong: the wall exerts a reaction force. (D) is wrong: friction can balance the push, so the man can be in equilibrium. Wrong statements: (A, C, D).
