The ratio of the accelerations due to gravity on two planets

P_1 \& P_2

is

K_1

. The ratio of their respective radii is

K_2

. The ratio of their respective escape velocities is

View answer and explanation

Correct option: A

\sqrt{k_1 k_2}

Option A (

\sqrt{{k_1 k_2}}

) is correct because the escape velocity is proportional to the square root of the product of the acceleration due to gravity and the radius.

The escape velocity for a body projected vertically upwards from the surface of the earth is

11.2\mathrm{\;\;km}{\mathrm{s}^{ - 1}}

. If the body is projected in a direction making an angle of

{45^0}

with the vertical, the escape velocity will be The escape velocity of a body projected from the surface of earth is

v_e

. If the body is projected at an angle

\theta

to the horizontal surface of earth, then the escape velocity would be If different planets have the same density but different radii, then the acceleration due to gravity on the surface of the planet is related to the radius (R) of the planet as Which of the following statement is absolutely correct about mass Statement I: An astronaut in a satellite feels weightlessness:

Statement II: As observed by another astronaut's in the same satellite, force of gravity and centrifugal force balance each other. An iron ball and a wooden ball of the same radius are released from a height 'h' in vacuum. The time taken by both of them to reach the ground is
