Statement (I) : The force of attraction due to a hollow
spherical shell of uniform density on a point mass situated
inside it is always positive .
Statement (II) : The force of attraction between a hollow
spherical shell of uniform density and a point mass
situated outside is same just as if the entire mass of the
shell is at the centre of the shell.
Which of the following is correct?
Options
- ABoth statements I and II are true
- BStatement I is true, but statement II is false
- CStatement II is true, but statement I is false
- DBoth statements I and II are false
Correct answer
C. Statement II is true, but statement I is false
Step-by-step solution
Inside the shell, E = 0
So, no net force will act on the point mass.
So (I) is false.
Also, hollow spherical shell behaves like point charge
placed at center of shell for every point outside the shell.
So, (II) is correct
