Answer:
a) N = 343 [N]
Explanation:
We must remember Newton's third law, which tells us that the force acting on a body is equal to the normal reaction force of equal magnitude but acting in the opposite direction.
[tex]N=m*g[/tex]
where:
m = mass = 35 [kg]
g = gravity acceleration = 9.81 [m/s²]
[tex]N = 35*9.8\\N= 343 [N][/tex]
