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 off mass m is kept. The minimum coefficient of friction `mu_m` in between the mass and the inclined surface such that the mass does not move is:

A

`tan 2theta`

B

`tan theta`

C

`3 tan theta`

D

`2 tan theta`
