Hello dear

escape velocity of any planet is given by

V_e = (2GM/R)^1/2 or (2GR)^1/2

where M is the mass of that planet and R is the radius of that planet.ang G is gravitational constant

Cheers..........................

the gravitational potential of a body on a planet is -GMm/R

for a body to escape the planet a kinetic energy >= the magnitude of this gravitional potential has to b produced

so, 1/2mv²=GMm/R

v=(2GM/R)^1/2

where M-mass of planet R-radius of planet
