A) 2.5 N
B) 5 N
C) 7.84 N
D) 10 N
Correct Answer: A
Solution :
Applied force \[=2.5\ N\] Limiting friction \[=\mu mg=0.4\times 2\times 9.8=7.84\ N\] For the given condition applied force is very smaller than limiting friction. \[\therefore \] Static friction on a body = Applied force = 2.5 NYou need to login to perform this action.
