The value of 'g' is ________-

The correct answer is 9.8 m/s2.

Key Points

• The value of 'g' is 9.8 m/s2
• • Where.
  • g = gravitational acceleration
  • G = gravitational constant
  • M = mass of the field source
  • r = distance between the two point-like masses
  •  =unit vector directed from the field source to the smaller sample mass
• Thus value of g on earth is,
  • g = 

Additional Information

• Gravitational acceleration is the acceleration of an object in free fall within a vacuum.
  • This is the steady gain in speed caused exclusively by the force of gravitational attraction. Wikipedia
  • g is referred to as the acceleration of gravity.
  • Its value is  on Earth.
    • That is to say, the acceleration of gravity on the surface of the earth at sea level is 
  • When discussing the acceleration of gravity, it was mentioned that the value of g is dependent upon location.
  • There are slight variations in the value of g about the earth's surface.
    • These variations result from the varying density of the geologic structures below each specific surface location.
