If the mass of the sun were ten times smaller and the universal gravitational constant were ten times larger in magnitude, which of the following statement will not be correct?

The kinetic energies of a planet in an elliptical orbit around the Sun, at positions A, B and C are K_A, K_B and K_C respectively. AC is the major axis and SB is perpendicular to AC at the position of the Sun S, as shown in the figure. Then:
               
 

If the acceleration due to gravity at a height 1 km above the earth is similar to a depth d below the surface of the earth, then: 

1. d=0.5 km

2. d=1 km

3. d=1.5 km

4. d=2 km

Two astronauts are floating in a gravitational free space after having lost contact with their spaceship. The two will:

(d) 

At what height from the surface of earth the gravitation potential and the value of g are $-5.4\times {10}^{7}J$ $k{g}^{-2}$ and $6.0$ $m{s}^{-2}$ respectively? (Take, the radius of earth as 6400 km.)

A satellite of mass \(m\) is orbiting the earth (of radius \(R\)) at a height \(h\) from its surface. What is the total energy of the satellite in terms of \(g_0?\)
( \(g_0\) is the value of acceleration due to gravity at the earth's surface )
1.   $\frac{m{g}_0{R}^2}{2(R+h)}$

2.  $-\frac{m{g}_0{R}^2}{2(R+h)}$

3.  $\frac{2m{g}_0{R}^2}{(R+h)}$
