Q. Explain about Centrifugal force?
The centrifugal force is
Fc =mv2/r,
Where r is the radius of the orbit and m is the mass of the object and v is the velocity. The orbital radius is assumed approximately equal to the earth's
Radius for low orbit, The gravitational force is
Fg = -mg,
Where g is the acceleration due to gravity, We are again assuming low orbit.
Then Fc + Fg = 0 and
mv2/r= mg
v2= gr, and,
v =√gr.
Assuming earth's radius to be 3960 miles and the acceleration due to gravity is 32 feet per second2 , we have
v = √32/5280 × 3960
v = 4.9mi/sec.
