Laws of Motion question

2016 · 9 Apr · Shift 1 · Q67

JEE MainPhysicsLaws of MotionMCQ+4 / −1
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\thetaθ with the horizontal, a point object of mass m is kept. The minimum coefficient of friction μ\muμ min between the mass and the inclined surface such that the mass does not move is :
  1. A
    tan θ\thetaθ
  2. B
    2tan θ\thetaθ
  3. C
    3tan θ\thetaθ
  4. D
    tan2 θ\thetaθ
