Imagine a new planet having the same density as that of the Earth but \(3\) times bigger than the Earth in size. If the acceleration due to gravity on the surface of the earth is \(g\) and that on the surface of the new planet is \(g',\) then:
1. \(g' = 3g\) 2. \(g' = 9g\)
3. \(g' = \frac{g}{9}\) 4. \(g' = 27g\)

The acceleration due to gravity at a height \(1~\text{km}\) above the earth's surface is the same as at a depth \(d\) below the surface of the earth. Then:

1. \(d= 1~\text{km}\) 2. \(d= \frac{3}{2}~\text{km}\)
3. \(d= 2~\text{km}\) 4. \(d= \frac{1}{2}~\text{km}\)

Choose the correct alternative.

1. Acceleration due to gravity increases with increasing altitude.
2. Acceleration due to gravity remains unchanged with increasing altitude.
3. Acceleration due to gravity increases with increasing depth (assume the earth to be a sphere of uniform density).
4. Acceleration due to gravity decreases with increasing depth (assume the earth to be a sphere of uniform density).
