Question

Intensity of the gravitational field inside the solid sphere is
(a) variable (proportional to distance from centre)
(b) constant
(c) variable (does not depend on distance from the centre)
(d) zero

Answer 1

$\huge\fcolorbox{red}{pink}{Answer}$

✏ Intensity of the gravitational field inside the solid sphere is given by...

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \dag \: \underline{ \boxed{ \bold{ \rm{ \pink{E = \frac{ Gmr}{ {R}^{3}}}}}}} \: \dag \\ \\ \therefore \rm \: E \propto \: r$

✏ r = distance from centre and R = Radius of sphere.

✏ As per ⬆ relation it is clear that Gravitational field is variable inside the sphere and proportional to distance from centre.
