Question

express escape velocity in terms of g and R​

Answer 1

Answer:

escape velocity =√2gr

hope it helps

Answer 2

Answer:

the energy required to escape the Earth's gravitational field is GMm / r, a function of the object's mass (where r is the radius of the Earth, G is the gravitational constant, and M is the mass of the Earth, M = 5.9736 × 1024 kg).

M is the mass of the planet, R is its radius, and G is the gravitational constant. It is equal to G = 6.674 × 10-11 N·m²/kg² . where m is the mass of the starting object, and v is the escape velocity.
