Question
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(r < R), then the correct option(s) is(are) :-
own gravity. If P(r) is the pressure at r(r < R), then the correct option(s) is(are) :-
Options
A.P(r = 0) = 0
B.
C.
D.
Solution
dF = [P - (P + dP)]A
⇒
dm = - (dP)A⇒
∴
