A block of mass M slides down on a rough inclined plane with constant velocity. The angle made by the incline plane with horizontal is θ. The magnitude of the contact force will be :

Multiple Choice Options

  • A Mg
  • B Mgcos⁡θ
  • C Mgsin⁡θ+Mgcos⁡θ
  • D Mgsin⁡θ1+μ

Step-by-Step Verified Solution

As the body is moving with constant velocity so forces acting on the body must be balanced.

⇒ Contact force from incline should balance weight of the body.

⇒ | Fcontact | = Mg
