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?
- A Both statements I and II are true
- B Statement I is true, but statement II is false
- C Statement II is true, but statement I is false
- D Both statements I and II are false
Answer & Solution
Correct Answer
(C) Statement II is true, but statement I is false
Step-by-step Solution
Detailed explanation
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
