Which of the following statement about the variation of gravitational field strength is true?
It increases as we go above the surface of the earth
It increases as we go below the surface of the earth
It's magnitude is maximum at the surface of the earth
None of the above is true
As we learn
Gravitational field Intensity -
Space or surrounding in which a material body feels the gravitational force of attraction.
It is denoted by I
If the mass of a body is m then I is given by
For a test mass gravitational force acting due to earth is mg
So gravitational field strength will be equal to g value.
So the value of the gravitational field strength is maximum at the surface of the eath.
