A block of mass M lies on a rough surface of coefficient of friction \(\mu\) A force is applied on it an angle \(\theta\) to the horizontal as shown, and the block is at rest. The frictional force acting on the block will be:
- \(F \cos \theta\)
- \(m(m g+F \sin \theta)\)
- \(m(m g-F \sin \theta)\)
- \(\mu m g\)
Answer
(A) F
