To correctly answer this question about the properties of paramagnetic substances, let's break down each statement:
Based on the above analysis, statements A and C are correct. Therefore, the most appropriate answer is A, C Only.
Paramagnetic substances exhibit the following characteristics:
Align themselves along the direction of an external magnetic field due to unpaired electrons.
Are weakly attracted to an external magnetic field.
Possess a magnetic susceptibility \( \chi > 0 \), but it is small and positive.
Do not move from strong to weak fields (this is a property of diamagnetic substances).
Final Answer: A, C only
| Group-I | Group-II | ||
| P | Magnetic | 1 | Chargeability |
| Q | Gravity | 2 | Electrical conductivity |
| R | Magnetotelluric | 3 | Susceptibility |
| S | Induced Polarization | 4 | Density |

If A and B are two events such that \( P(A \cap B) = 0.1 \), and \( P(A|B) \) and \( P(B|A) \) are the roots of the equation \( 12x^2 - 7x + 1 = 0 \), then the value of \(\frac{P(A \cup B)}{P(A \cap B)}\)
