Write true or false for the following statements:

Acceleration due to gravity is expressed as


g =


Where, symbols have their usual meanings.

True

Explanation:


The acceleration produced in a freely falling body by the gravitational pull of the earth is called the acceleration due to gravitation.


We know that,


Force = Mass × Acceleration


F = m × a


a = …..1


Where, F is the force on the object of mass m dropped from a distance r from the centre of earth of mass M.


So, force exerted by the earth on the object is


F = …..2


M = Mass of Earth


m = mass of object


r = distance of object from centre of earth


Now, from equation 1 and 2,


a =


a =


Now, from above,


a = g = Acceleration due to gravity


Hence,


g =
