Assertion (A) and Reason (R) type questions. Two statements are given one labelled Assertion (A) and the other labelled Reason
(R). Select the correct answer from the codes (A), (B), (C) and (D) as given below.

Assertion (A) : An electron and a proton enter with the same momentum \(\vec{\mathrm{p}}\) in a magnetic field \(\vec{\mathrm{B}}\) such that \(\vec{\mathrm{p}}⊥\vec{\mathrm{B}}\). Then both describe a circular path of the same radius.

Reason (R) : The radius of the circular path described by the charged particle (charge \(q\), mass \(m\) ) moving in the magnetic field \(\vec{B}\) is given by \(r=\frac{mv}{qB}\).
