A mass m can be kept on the x-axis. At
Column I | Column II | ||
(i) | (P) | Stable equilibrium | |
(ii) | (Q) | Unstable equilibrium | |
(iii) | (R) | Neutral equilibrium | |
(S) | Not in equilibrium |

Text Solution
Verified by ExpertsThe correct answer is:
A
At 
is + ve, i.e., 
is minimum and is in stable equilibrium.
For 
is not zero, i.e., not stable equilibrium.
At 
is - ve 
is max, i.e., unstable equilibrium.
