Question

Given below are two statements: one is labelled asAssertion Aand the other is labelled asReason R.
Assertion A:. If oxygen ion $(O^{- 2})$ and Hydrogen ion $(H^{+})$ enter normal to the magnetic field with equal momentum, then the path of $O^{- 2}$ ion has a smaller curvature than that of $H^{+}$ .
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 correctanswer from the options given below :

Options:

Answer:

A

Solution:

$r = \frac{m v}{qB} = \frac{p}{qB} r \propto \frac{1}{q}$
