A box of mass 8 kg is placed on a rough inclined plane of inclination \(\theta\). Its downward motion can be prevented by applying an upward pull F and it can be made to slide upwards by applying a force 2 F. The coefficient of friction between the box and the inclined plane is:
- \(\frac{1}{3} \tan \theta\)
- 3 tan\(\theta\)
- \(\frac{1}{2} \tan \theta\)
- 2 tan\(\theta\)
