a pieces of metal of mass 3.6kg is suspended from a spring balance, what is the reading of spring balance in newton, with a metal in air, with the metal of 33newton
To find the reading of the spring balance, you need to use Newton's second law of motion, which states that the force (F) acting on an object is equal to the mass (m) of the object multiplied by its acceleration (a). In this case, the force acting on the metal suspended from the spring balance is equal to its weight.
The weight of an object is given by the formula:
Weight (W) = mass (m) × acceleration due to gravity (g)
In this case, the mass of the metal is 3.6 kg, and the acceleration due to gravity is approximately 9.8 m/s².
So, the weight of the metal is:
Weight (W) = 3.6 kg × 9.8 m/s² = 35.28 N
Therefore, when the metal is in the air, the reading on the spring balance will be approximately 35.28 Newtons.
