The dependence of acceleration due to gravity gg on the distance rr from the centre of the earth, assumed to be a sphere of radius RR of uniform density is as shown in figures below (1) The dependence of acceleration due to gravity g on the distance r from the centre of the earth, assumed to be a sphere
(2)The dependence of acceleration due to gravity g on the distance r from the centre of the earth, assumed to be a sphere
(3)The dependence of acceleration due to gravity g on the distance r from the centre of the earth, assumed to be a sphere
(4)The dependence of acceleration due to gravity g on the distance r from the centre of the earth, assumed to be a sphere
The correct figure is

Options

  1. A(4)
  2. B(1)
  3. C(2)
  4. D(3)

Correct answer

A. (4)

Step-by-step solution

∵g∝r\because g \propto r and g∝1r2g \propto \frac{1}{\mathbf{r}_2} (if r<Rr < R ) (if r>Rr>R ) So, the correct figure will beThe dependence of acceleration due to gravity g on the distance r from the centre of the earth, assumed to be a sphere
