Define escape velocity of an object.

Three equal masses (each m) are placed at the corners of an equilateral triangle of side a'. Then the escape velocity of an object from the circumcentre P of triangle is

Define velocity of an object

The escape velocity of an object projected from the surface of a given planet is independent of

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

What would be the duration of the year if the distance between the eath and the sun gets doubled ? Will this affect the escape velocity of an object on the surface of earth ?

The escape velocity of an object on a planet whose radius is 4 times that of the earth and g value 9 tims that on the earth, in Kms^(-1) , is
