A person is managing to be at rest between two vertical walls by pressing one wall by his hands and feet and second wall with his back. The coefficient of friction is between his body and the wall. If the force with which the person pushes the wall is then the mass of the person is (Take )
- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
Normal reaction at person by wall are equal, as body is at rest, net horizontal force must be equal. Let us assume normal reaction to be N And as per given question, N=500 N From vertical equilibrium, we have ⇒2f=W ⇒2μN=mg ⇒m=2μNg…
