The figure shows a horizontal force F⃗\vec{F} acting on a block of mass M\mathrm{M} on an inclined plane (angle θ\theta ). What is the normal reaction NN on the block? The figure shows a horizontal force F acting on a block of mass M on an inclined plane (angle θ ). What is the normal

Options

  1. Amgsin⁡θ+Fcos⁡θm g \sin \theta+F \cos \theta
  2. Bmgsin⁡θ−Fcos⁡θm g \sin \theta-F \cos \theta
  3. Cmgcos⁡θ−Fsin⁡θm g \cos \theta-F \sin \theta
  4. Dmgcos⁡θ+Fsin⁡θm g \cos \theta+F \sin \theta

Correct answer

D. mgcos⁡θ+Fsin⁡θm g \cos \theta+F \sin \theta

Step-by-step solution

The figure shows a horizontal force F acting on a block of mass M on an inclined plane (angle θ ). What is the normal
From the figure, the normal reaction on the block is N=mgcos⁡θ+Fsin⁡θN=m g \cos \theta+F \sin \theta.
