Which one of the following plots represents the variation of gravitational field F on a particle with distance r due to a thin spherical shell of radius R?
( r is measured from the centre of the spherical shell)
A
B
C
D
Answer
Explanation
Solution
Gravitational field due to the thin spherical shell. Inside the shell,
F = 0 (For r < R)
On the surface of the shell.
(For r = R)
Outside the shell,
(For r > R)
The variation of F with distance r from the centre is as shown in the figures.
