The magnitudes of the gravitational field at distances r₁ and r₂ from the centre of a uniform solid sphere of radius R and mass M are F (r₁ ) and F (r₂ ) respectively. Such that

Options

AF ( r ₁ ) F ( r ₂ ) = r ₁ r ₂ if r ₁ R and r₂ R
BF ( r ₁ ) F ( r ₂ ) = r ₂^2 r ₁^2 if r ₁ R and r₂ R
CF ( r ₁ ) F ( r ₂ ) = r ₁ r ₂ if r ₁ R and r₂ R
DF ( r ₁ ) F ( r ₂ ) = r ₁^2 r ₂^2 if r ₁ R and r₂ R

Correct answer

B. F ( r ₁ ) F ( r ₂ ) = r ₂^2 r ₁^2 if r ₁ R and r₂ R

At a certain height h above the surface of the earth the change in the value of acceleration due to gravity (g) is the same as that at a depth x below the surface. Assuming h and x If Newton's inverse square law of gravitation had some dependence on radial distance other than r⁻² , which one of Kepler's three laws of planetary motion would rNone of the above Let R be the radius of the earth. In general, the loss of gravitational potential energy of a body of mass m falling from a height h to the earth surface is A satellite is launched from a point close to the surface of the earth (radius R ) with a velocity v=v₀ 1.5 , where v₀ is the velocity in a circular orbit.
