Question

Drive the relation between gravity at the equator and gravitation?​

Answer 1

Explanation:

To calculate the value of g, we should put the values of G, M and R

Where G=universal gravitational constant, G=6.7×10

–11

Nm

2

kg

−2

mass of the earth, M=6×10

24

kg,

and radius of the earth, R=6.4×10

6

m.

g=

R

2

GM

g=

(6×10

6

)

2

6.67×10

−11

×6×10

24

=9.8m/s

2

Thus, the value of acceleration due to gravity of the earth, g=9.8m/s

2

Also we know Weight in nothing but the force exerted by the earth with a value of acceleration =9.8m/s

2

Now at the poles the value of acceleration due to gravity is higher as compared to the equator as the constant value of

g depends on the radius of the earth which decreases when we come down from poles to the equator.
