Question

1) Which of the following is true?

a) The acceleration due to gravity acting on a freely falling body is

directly proportional to the mass of the body

b) Mass of the object is same on Moon and Earth

c) G value is always constant

d) The weight of an object at the center of earth will be zero​

Answer 1

The explaination of the given problem is as follows:

(a)True

(b) False: The gravity does not require a medium. The gravity in the black hole is strong even if it is in a vacuum.

(c) False: The value of G always remains constant irrespective of the location.

(d) False: The acceleration produced in a freely falling body is independent of the mass of the body

(e) False: The weight of the object on the moon = (1/6) × its weight on the earth.
