A trolley is accelerating down an incline of angle $\theta$ with acceleration $g \sin \theta$. Which of the following is correct. $(\alpha$ is the constant angle made by the string with vertical)

A

$\alpha=0^0$

B

$\alpha=\theta$

C

Tension in the string, $T = mg$

D

Tension in the string, $T=m g \sec \theta$

Solution

From trolley frame $m g \sin \alpha=m g \sin \theta$

$\theta=\alpha$
