AI Generated Solution

To determine the charge on an alpha particle in relation to the charge on a proton, follow these steps: ### Step 1: Understand the Composition of an Alpha Particle An alpha particle is essentially the nucleus of a helium atom. It consists of 2 protons and 2 neutrons. ### Step 2: Determine the Charge of a Proton The charge of a single proton is +1 elementary charge (approximately +1.6 x 10^-19 coulombs). ...

If an alpha particle, proton and deuteron are projected perpendicularly a uniform magnetic field with same speed then let r_(alpha) is the radius of alpha -particles, r_(P) is radius of proton, rd is radius of deuteron.

Statement 1: If a proton and an alpha -particle enter a uniform magnetic field perpendicularly with the same speed, the time period of revolution of alpha -particle is double than that of proton. Statement 2: In a magnetic field, the period of revolution of a charged particle is directly proportional to the mass of the particle and inversely proprotional to the charge of particle.
