356543 Assertion :
\(\alpha \) and \(\beta \) particles are accelerated through same potential difference. Finally both particles have same linear momentum.
Reason :
Linear momentum \( = \sqrt {KE \times 2 \times mass} \)

356545 The radiation corresponding to \(3 \to 2\) transition of hydrogen atom falls on a metal surface to produce photoelectrons. These electrons are made to enter a magnetic field of \(3 \times {10^{ - 4}}T.\) If the radius of the largest circular path followed by these electrons is \(10.0\,mm\), the work function of the metal is close to :
