Explanation The formula for escape speed is, v e = 2 G M p R p (1) Here, v e is the escape speed of object. M p is the mass of the planet. R p is the radius of the planet. G is the universal gravitational constant. For earth, substitute v e e for v e , M e for M p and R e for R p in the above expression. v e e = 2 G M e R e (2) For distant planet,

Central Force

Central force is the force that acts along the center of mass of one body to the center of mass of another body. Its direction from or away from a point on a body to another is called the center of the force. Such forces include gravitational force betwe…
