Question
The magnitudes of the gravitational field at distance r1 and r2 from the centre of a uniform, sphere of radius R and M are F1 and F2 respectively. then : -
Options
A.
if r1 < R and r2 < R
if r1 < R and r2 < RB.
if r1 < R and r2 < R
if r1 < R and r2 < RC.
if r1 < R and r2 < R
if r1 < R and r2 < RD.
if r1 < R and r2 < R
if r1 < R and r2 < RSolution
Gravitational field intensity F = 
Inside the sphere
(F1 ∝ r1, F2 ∝ r2)
of r1 < R & r2 < R
Gravitational field intensity
I ∝
(Out side the sphere)
∴
if r1 > R and r2 > R
Inside the sphere
(F1 ∝ r1, F2 ∝ r2)
of r1 < R & r2 < RGravitational field intensity
I ∝
(Out side the sphere)∴
if r1 > R and r2 > RCreate a free account to view solution
