The charge on a proton is +1.6 × 10 −19 C and that on an electron is −1.6 × 10 −19 C. Does it mean that the electron has 3.2 × 10 −19 C less charge than the proton?

The Alpha Particle Scattering Experiment. They took a thin gold foil having a thickness of 2.1×10-7 m and placed it in the centre of a rotatable detector made of zinc sulfide and a microscope. Then, they directed a beam of 5.5MeV alpha particles emitted from a radioactive source at the foil.

An alpha particle (q = +2e, m = 4.00 u) travels in a circular path of radius 5.52 cm in a uniform magnetic field with B = 1.07 T. Calculate (a) its speed, (b) its period of revolution, (c) its kinetic energy, and (d) the potential difference through which it would have to …

An alpha particle (consisting of two protons and two neutrons) is moving in a circle at constant speed, perpendicular to a uniform magnetic field applied by some current-carrying coils. The alpha particle makes one clockwise revolution every 84 nanoseconds (see the figure). O If the speed is small compared to the speed of light, what is the ...

One characteristic that makes alpha radiation different from beta and gamma radiation is the type of radioactive decay it emits. Which description best describes an alpha particle? O An alpha particle is attracted to a positive electrode. O An alpha particle has no atomic number. O An alpha particle has no mass.

The alpha particles contain four subatomic particles viz. two protons and two neutrons. Helium atom (H e 2 +) also contain two neutron and two protons. Thus α − particles are called as nuclei of Helium atom.

The closest distance of approach of an α − particle travelling with a velocity v towards Al (Z = 13) nucleus is d. The closest distance of approach of an α − particle travelling with velocity 4 v towards Fe (Z = 26) nucleus is-

An electron, a proton, a deuteron and an α − particle are accelerated by the same potential V. If λ e, λ p, λ d and λ α represents the de-Broglie wavelengths of electron, proton, deuteron and α − particle respectively. Which of the following statement(s) is/are correct.

Complete the table (Table 2) below.

In the space below, use X for symbol of an element, Z for atomic number and A for mass number. 1.

An alpha particle in an unstable nucleus can be modeled as a particle with a specific energy, bouncing back and forth between these square potential barriers. Each time the alpha particle comes into contact with a potential barrier, there is some probability T that it will tunnel out.
