The acceleration of a body sliding down the inclined plane, having coefficient of friction ' \(\mu\) ', is
- A \(a=g(\sin \theta+\mu \cos \theta\)
- B \(a=g(\sin \theta-\mu \cos \theta)\)
- C \(a=g(\cos \theta-\mu \sin \theta)\)
- D \(a=g(\cos \theta+\mu \sin \theta)\)
Answer & Solution
Correct Answer
(B) \(a=g(\sin \theta-\mu \cos \theta)\)
Step-by-step Solution
Detailed explanation
The acceleration of the body down the inclined plane is \(\begin{aligned} & a=\frac{F_{\text {net }}}{M}=\frac{(m g \sin \theta-\mu m g \cos \theta)}{m} \\ & =g(\sin \theta-\mu \cos \theta) \end{aligned}\)
