Question

Gravitational force acts on all objects in proportion to their masses, still a heavy object does not fall faster than a light object because

• A. of the air friction
• B. acceleration due to gravity does not depend upon the mass of an object
• C. during falling, masses are considered negligible
• D. because heavy object produces less acceleration due to gravity as compared to light object

Answer 1

The correct option is B

acceleration due to gravity does not depend upon the mass of an object

The gravitational force $F$ acting on a body of mass $m$ near the surface of earth is given by
$F=G\frac{M\times m}{R^2}$
where, $R=$ Radius of the earth
and $M=$ Mass of the earth
Acceleration, $g=\frac{F}{m}=G\frac{M}{R^2}$
This value is constant (if we neglect air resistance) and does not depend upon the mass of an object. Hence, heavy objects do not fall faster than light objects.
