(A): | The plot of V against r is discontinuous. |
(B): | The plot of E against r is discontinuous. |
1. | Both A and B are correct |
2. | A is correct but B is wrong |
3. | B is correct but A is wrong |
4. | Both A and B are wrong |
Let \(V\) and \(E\) be the gravitational potential and gravitational field at a distance \(r\) from the centre of a uniform spherical shell. Consider the following two statements:
(A) | The plot of \(V\) against \(r\) is discontinuous. |
(B) | The plot of \(E\) against \(r\) is discontinuous. |
1. | Both (A) and (B) are correct. |
2. | (A) is correct but (B) is wrong. |
3. | (B) is correct but (A) is wrong. |
4. | Both (A) and (B) are wrong. |
Assertion (A): | Gravitational potential is constant everywhere inside a spherical shell. |
Reason (R): | Gravitational field inside a spherical shell is zero everywhere. |
1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
3. | (A) is True but (R) is False. |
4. | Both (A) and (R) are False. |
