Question

A body of mass
is placed on a frictionless
Cas shown in the sketch)
inclined
plane
block's weight
The component
the
direction parallel to the inclined plane
given​

Answer 1

Answer:

Breakout the gravity force vector into components which are parallel -mg*sin(Θ) and perpendicular -mg*cos(Θ) to the incline. The normal force will be equal and opposite to the perpendicular gravity component so N = +mg*cos(Θ).
