Question

A block of mass 1 kg is resting over a rough inclined plane and a force F of magnitude 2 N is applied vertically upward as shown in figure, then magnitude of net contact force (in N) on the block by the inclined plane will be

F=2N Rough surface i l g <37 

Answer 1

F.B.D

Since block is at rest
(\Rightarrow \vec {F_C}+\vec {F}+m\vec {g}=0\)

$\Rightarrow \overrightarrow{F_C}=8N\hat{j}$
