Question

What is the magnitude of fs on an object lying on a flat surface without moving, on
which a force F = 10 N is acting?

Answer 1

The magnitude of the force acting on the object lying on a flat surface without moving is 10 N.

The given parameters;

• magnitude of force on the object, F = 10 N

• angle between the object and the horizontal flat surface = 0⁰

Apply Newton's second law of motion to determine the magnitude of the force on the object.

Due to the position of the object, the magnitude of the force acting on it is calculated as;

$\Sigma F_{net} = F\sin(\theta ) + F cos(\theta)\\\\\Sigma F_{net} = 10 sin(0) + 10cos(0)\\\\\Sigma F_{net} = 10 \ N$

Therefore, the magnitude of the force acting on the object is 10 N.
