Question

The charge and mass of electrons is equal to that of
A) X-Rays
B) Gamma-Ray
C) Alpha-Rays
D) Beta-Rays​

Answer 1

d=beta rays

It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1093837015 × 10−31 kg, which is only 1/1,836the mass of a proton.

Answer 2

D) Beta-Rays

• A beta flyspeck, also called beta shaft or beta radiation( symbol β), is a high- energy, high- speed electron or positron emitted by the radioactive decay of an infinitesimal nexus during the process of beta decay.
• There are two forms of beta decay, β − decay and β decay, which produce electrons and positrons independently .
• Beta patches with an energy of0.5 MeV have a range of about one metre in air; the distance is dependent on the flyspeck energy.
• Beta patches are a type of ionizing radiation and for radiation protection purposes are regarded as being further ionising than gamma shafts, but lower ionising than nascence patches.
• The advanced the ionising effect, the lesser the damage to living towel, but also the lower the piercing power of the radiation.
