Which of the following statements is absolutely correct about mass?
Correct answer: C. More the mass of a body, lesser will be its acceleration for a given force.
- A. More the mass of a body connected with spring balance, more will be the elongation in the spring balance.
- B. More the mass of body kept in one pan of beam balance, more the mass has to be kept on the other pan to keep beam horizontal.
- C. More the mass of a body, lesser will be its acceleration for a given force.
- D. All of the above
Explanation
This is the following solution: Consider the situation in gravity-free space. From Newton's second law of motion, F = ma Here, F = Force on mass m, m = Mass of the object, a = Acceleration of the object Now, for a constant force, m ∝ 1/a From the above relation, we can say that, if the mass of a body increases, its acceleration decreases.Out of the given statements, option 'C' is the correct answer as it is absolutely correct. The other statements are either partially correct or correct but not absolute. Mass plays a significant role in physics and is measured using various instruments such as spring balance, beam balance, etc.

About Gravitation
Newton’s law of universal gravitation relates the force between masses to their masses and separation, while gravitational field strength explains weight and orbital motion. The topic covers satellite velocity and period, escape ideas, weightlessness in free fall, and artificial gravity, which differs from ordinary gravitational attraction.
