JEE Mains · Physics · STD 12 - 5. Magnetism and matter
Choose the correct option:
- A True dip is not mathematically related to apparent dip.
- B True dip is less than apparent dip.
- C True dip is always greater than the apparent dip.
- D True dip is always equal to apparent dip.
Answer & Solution
Correct Answer
(B) True dip is less than apparent dip.
Step-by-step Solution
Detailed explanation
If apparent dip circle is at an angle \(\alpha\) with true dip circle then True dip circle \([Image]\) Apparent dip circle \([Image]\) As \(\cos \alpha\,<1\) Hence true \(\operatorname{dip}(\phi)\) is less than apparent \(\operatorname{dip}\left(\phi^{\prime}\right)\)
