Questions
A block of mass 5 kg is placed on a horizontal surface with coefficient of friction = 0.2, then the maximum and minimum value of force F for which the block remains at rest are (g = 10 )
detailed solution
Correct option is B
If it has to move right, frictional force 0.2 x 5 x 10 = 10 N acts towards left then maximum F value should be 25 Nif it has to move towards left, frictional force acts towards right. Net force 15 -10 = 5 N has to be applied towards right.Talk to our academic expert!
