A body is made to move up along an inclined plane of inclination 30^ and the coefficient of friction is 0.5 , then its retardation is ( g - acceleration due to gravity)

Options

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

Correct answer

A. ( 2+ 3 4 ) g

Step-by-step solution

Retardation, a=g( + )= g [ 30^ +0.5 ( 30^ ) ] =g ( 1 2 + 1 2 3 2 )= ( 1 2 + 3 4 ) g = ( 2+ 3 4 ) g
