A block of mass m is at rest on an inclined surface having a coefficient of friction \(\mu>\tan \theta\) as shown in the figure. The horizontal acceleration which should be given to the inclined plane, so that the force of friction between the block and the plane becomes zero, is:
- g sin \(\theta\), leftward
- \(g \tan \theta\), leftward
- g cot \(\theta\), rightward
- \(g \tan \theta\) rightward
Answer
(B) g , leftward, (C) g cot , rightward
