JEE Main 2025 — Magnetic Effects of Current Question with Solution
JEE Main 2025 (3 Apr Shift 2)
Question
Given below are two statements: one is labelled as Assertion A and the other is labelled asReason R.
Assertion A:. If oxygen ion and Hydrogen ion enter normal to the magnetic field with equal momentum, then the path of ion has a smaller curvature than that of .
Reason R : A proton with same linear momentum as an electron will form a path of smaller radius of curvature on entering a uniform magnetic field perpendicularly.
In the light of the above statements, choose the correct answer from the options given below :
