Question

On what factors do the changes occurring in the g depend ?​

Answer 1

Explanation:

The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.

PLZ MARK THIS ANSWER AS BRAINLIEST FIRST. HOPE IT HELPS.

As you know, 'g' is acceleration due to gravity on Earth.

g = G × $\frac{M}{R^2}$

Where 'g' is the acceleration due to gravity, 'G' is the universal gravitation constant, 'M' is the mass of the Earth and 'R' is the radius of the Earth.

∴ g = 6.67259 x 10-11 × $\frac{5,972,000,000,000,000,000,000,000 }{6,370,000}$ (it wont allow me to put scientific notations so heres the scientific notations, Mass of Earth = 5.972 × $10^{24}$ kg and Radius of Earth = 6.37 × $10^{6}$ m)

That is the value of 'g', or at least the average value. If you look at the picture of Earth carefully, you may notice that it is not a perfect sphere (I have a diagram down below). Because of this, the radius of the Earth changes from place to place, this change in radius affects the denominator of our equation, hence, lesser the radius, more the value of 'g' and more the radius, lesser the value of 'g'. This can be properly noticed at the poles and the equator. The equator is bulged, having more radius than the poles, as a result weight of a body is more at the poles than at the equator.

I hope this answer helped, thank you. BTW diagram below and plz mark brainliest
