Question

Find the value of $\theta$ such that the acceleration of $A$ is $g/6$ downward along the incline plane. (All surfaces are smooth)

• A. $\theta ={10}^o$
• B. $\theta ={60}^o$
• C. $\theta ={45}^o$
• D. $\theta ={53}^o$

Answer 1

Answer: (A)

$\theta ={10}^o$

This can be given by equation,

$mg\sin \theta =\frac{mg}{6}$

So,

$\theta ={9.59}^{\circ }$
