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.
