Planet $A$ has mass $M$ and radius $R$, planet $B$ has mass $M/3$ and radius $3R$. If escape velocity from planet $A$ is $V_e$, then escape velocity from planet $B$ will be

Q. If $V_e$ is the escape velocity of a body from a planet of mass $M$ and radius $R$. Then, the velocity of satellite revolving at height $h$ from the surface of planet will be

Q. If $V_e$ is the escape velocity of a body from a planet of mass M and radius R. Then the velocity of the satellite revolving at height h from the surface of the planet will be:

Q. Planet $A$ has mass $M$ and radius $R$. Planet $B$ has half the mass and half the radius, that of Planet $A$. If the escape velocities from the Planets $A$ and $B$ are $V_A$ and $V_B$, respectively, then $\frac{v_A}{v_B}=\frac{n}{4}$. The value of $n$ is:

Q. Escape velocity from a planet of mass $M$ and radius $R$ will be:
