A body of mass 2 ~kg is on an inclined plane of inclination 30^ and coefficient of friction is ( 1 3 ) . The minimum force required to move the body up the inclined plane is ( . Acceleration due to gravity .=10 ~ms ⁻² )

Options

  1. A5.77 ~N
  2. B10 ~N
  3. C20 ~N
  4. D15 ~N

Correct answer

C. 20 ~N

Step-by-step solution

Mass of body, m=2 ~kg For body moving up aligned & F=m g +f_r & =m g + _k N=m g + _k m g & =2 10 1 2 + 1 3 2 10 3 2 =20 N aligned
