Solution:
A force of produces an acceleration of on mass and an acceleration of on mass . The acceleration is if both the masses are tied together.Given,
Force of the first mass,
acceleration of first mass,
Force of second mass,
acceleration of first mass,
According to Newton’s second law of motion,
where is the force applied/exerted, is the mass and is the acceleration of the body.
For the first mass, on substituting the given values, we get
where is the mass of the first mass.
Similarly, for the first mass, on substituting the given values, we get
where is the mass of the second mass.
The total mass if the bodies are tied together is
Now, the acceleration produced by the same force provided if both the masses are tied together is
Hence, the acceleration is .
