Options

  1. AA small block of mass m is placed at the highest point of a smooth fixed sphere of radius R . It is given a horizontal
  2. BA small block of mass m is placed at the highest point of a smooth fixed sphere of radius R . It is given a horizontal
  3. CA small block of mass m is placed at the highest point of a smooth fixed sphere of radius R . It is given a horizontal
  4. DA small block of mass m is placed at the highest point of a smooth fixed sphere of radius R . It is given a horizontal

Correct answer

B. A small block of mass m is placed at the highest point of a smooth fixed sphere of radius R . It is given a horizontal

Step-by-step solution

gin=GMrR3⇒gin∝r{g}_{in} = \dfrac{GMr}{{R}^{3}} ⇒ {g}_{in} ∝ r.

gout=GMr2⇒gout∝1r2{g}_{out} = \dfrac{GM}{{r}^{2}} ⇒ {g}_{out} ∝ \dfrac{1}{{r}^{2}}.
