Which of the following graphs shows the variation of acceleration due to gravity $g$ with depth $h$ from the surface of the earth?

A point mass is placed inside a thin spherical shell of radius $ H $ and mass $ M $ at a distance $R/2$ from the centre of the shell. The gravitational force exerted by the shell on the point mass is.

If distance between earth and sun become four times then time period becomes

Escape velocity from a planet is $ V_{e}$ . If its mass is increased to $8$ times and its radius is increased to $2$ times, then the new escape velocity would be:
