Question

A rocket is fired vertically from the earth with an acceleration of 2g, where g is the gravitational acceleration. On an inclined plane inside the rocket, making an angle $\theta $ with the horizontal, a point object of mass m is kept. The minimum coefficient of friction $\mu $_min between the mass and the inclined surface such that the mass does not move is :

tan$\theta $

2tan$\theta $

3tan$\theta $

tan2$\theta $
