Either will do provided you bring all relevant forces acting on the mass into the equation.bomberkid said:
You get the right answer if you bring in all forces acting on the mass and do the algebra correctly. Please post your working.bomberkid said:
Newton's third law states that for every action, there is an equal and opposite reaction. This means that when an object exerts a force on another object, the second object will exert an equal and opposite force back on the first object.
The reaction force is the force exerted by the second object in response to the action force. According to Newton's third law, this reaction force will be equal in magnitude but opposite in direction to the action force.
One example is when you push against a wall, the wall pushes back on you with an equal and opposite force, preventing you from moving through the wall.
No, Newton's third law applies to all objects, whether they are in contact or not. For example, when a rocket propels itself forward, the exhaust gases are pushing against the rocket with an equal and opposite force.
Newton's third law can be observed in many everyday situations, such as walking, swimming, and driving a car. It also plays a crucial role in the design and function of various machines and structures, from bicycles to skyscrapers.
