The escape velocity of an object from th...

The escape velocity of an object from the earth depends upon the mass of the earth ( M ), its mean density `(rho)`, its radius ( R ) and the gravitational constant ( G ). Thus the formula for escape velocity is

A

`v=Rsqrt((8pi)/G rho)`

B

`v=Msqrt((8pi)/GR)`

C

`v=sqrt(2GMR)`

D

`v=sqrt((2GM)/R^(2))`
