What is the formula for the force of attraction between two point masses?
What is the formula for the force of attraction between two point masses?
- F = Gm1m2 / r^2 (correct)
- F = Gm1m2 * r^2
- F = Gm1m2 - r^2
- F = Gm1m2 + r^2
In which region is the acceleration due to gravity 'g' equal to 'gS'?
In which region is the acceleration due to gravity 'g' equal to 'gS'?
- Inside a region closer to the center of the Earth
- At a height greater than the radius of the Earth
- Inside a solid sphere
- On the surface of a spherical shell (correct)
What is the gravitational potential inside a solid sphere?
What is the gravitational potential inside a solid sphere?
- V = GM(R+h)^2
- V = GM / r
- V = 0 (correct)
- V = GM(3R^2 - r^2)
