Answer 2

The coefficient of friction between coin and plane = 0.577

Given:

• Coin of mass 10 g just begins to slide down a rough inclined plane of          inclination 30°

To find:

      The coefficient of friction between coin and plane.

Concept used:

• When a body just begins to slide down a rough inclined plane.
• Angle of friction = Angle of repose
• Coefficient of friction = $\tan(\text {Angle of friction })$

Explanation:

• From given data angle of repose = 30°
• body just begins to slide down a rough inclined plane.
• Angle of friction = Angle of repose
• Angle of friction = 30°
• Coefficient of friction = $\tan(\text {Angle of friction })$
• Coefficient of friction = $\tan }(\text {30})$

                                            = 0.577

• The coefficient of friction between coin and plane = 0.577
