Q.

Angle of friction is the

  • AAngle between normal reaction and the resultant of normal reaction and the limiting friction
  • BRatio of limiting friction and normal reaction
  • CThe ratio of minimum friction force to the friction force acting when the body is just about to move
  • DThe ratio of minimum friction force to friction force acting when the body is in motion
Correct Answer : (A)

Angle between normal reaction and the resultant of normal reaction and the limiting friction

Hints :
