A spherical body of radius R consists of a fluid of constant density and is in equilibrium under its own gravity. If P(r) is the pressure at r(rltR), then the correct option(s) is (are)

A

`P ( r=0 ) =0`

B

`( P ( r = 3 R //4))/(P ( r= 2R//3)) = ( 63)/( 80)`

C

`( P ( r = 3 R //5))/(P ( r= 2R//5)) = ( 16)/( 21)`

D

`( P ( r = R //2))/(P ( r= R//3)) = ( 20)/( 27)`
