Q. No.The potential energy of a particle in a force field is \(U=\dfrac{A}{r^2}-\dfrac{B}{r}\) where \(A\) and \(B\) are positive constants and \(r\) is the distance of the particle from the centre of the field. For stable equilibrium, the distance of the particle is:
| 1. | \(\dfrac{B}{A}\) | 2. | \(\dfrac{B}{2A}\) |
| 3. | \(\dfrac{2A}{B}\) | 4. | \(\dfrac{A}{B}\) |

The potential energy of a system increases if work is done:
| 1. | by the system against a conservative force |
| 2. | by the system against a non-conservative force |
| 3. | upon the system by a conservative force |
| 4. | upon the system by a non-conservative force |
