The value of the escape velocity from the earth is v_e . If the radius of a planet is 4 times that of the earth and its density is 9 times the density of the earth, then the value of the escape velocity from that planet will be

What is escape velocity?

The value of the escape velocity of a body thrown vertically upwards from the surface of the earth is v. if the body is thrown making an angle theta with the vertical, then the value of the escape velocity will be
