When a body slides down on inclined plane with coefficient of friction ( ), then its acceleration will be

Options

  1. A(g( - ) )
  2. B(g( + ) )
  3. C(g( - ) )
  4. D(g ( - ) )

Correct answer

A. (g( - ) )

Step-by-step solution

When a body of mass (m ) slides down on inclined plane with acceleration (a ), then various forces acting on the body are shown in the figure. According to Newton's second law of motion, ( aligned & & m a & =m g - R & & m a & =m g - m g & & a & =g - g & & a & =g( - ) aligned )
