Sagot :
Answer:
The magnitude of the normal force on the box is N= m*g + W
Explanation:
According to Newton's Second law and normal force.
- The resultant of the forces acting on the person must be equal to the product between the mass and the acceleration a of the person itself.
so with the help of Newton's second law
we can write the equation for force:
F = ma
Since,
box is sitting on floor of an elevator.
there are two forces acting on this box:
- W due to it's weight (downward)
- N due to the normal force of the floor against the body (upward).
So we can rewrite the previous equation as,
N - W = F
N - W = ma
hence,
N=m*a + W
this is the The magnitude of the normal force on the box.
