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 θ with the horizontal, a point object of mass m is kept. The minimum coefficient of friction μmin between the mass and the inclined surface such that the mass does not move is:
  1. tan⁡2θ
  2. tan⁡θ
  3. 3tan⁡θ
  4. 2tan⁡θ

Solution



3mgsin⁡θ=μ3mgcos⁡θ

μ=tan⁡θ
