Since the atom is electrically neutral there must be positively charged particles present in the atom to neutralize the negative charges of the electrons. Goldstein experimentally proved the existence of protons in the ato..

The proton has an equal and opposite to the charge of an electron. So, the absolute charge of a proton is 1.6 x 10 -19 coulomb of positive charge. This being the smallest positive charge carried by any particle, it is taken as 1 unit positive charge. The relative cha..

Alpha decay is the phenomenon of emission of an a - particle from radioactive nucleus...

Alpha rays consist of stream of positively charged particles carrying charge of +2 units and a mass of four units on the atomic weight scale (i.e., 4 amu). They consist of 2 protons and 2 neutrons. In other words, these particles are helium nuclei and there..

They get deflected by electric and magnetic fields. The deflection is large since a beta particle is lighter than an a -particle. They affect photographic plates. They ionise the gas through which they pass. The mass is 9.1 x 10 - 3 1 kg and its charge is 1.6x10 -..

Beta rays are made up of streams of negatively charged particles similar to electrons. Thus, - particle has a unit negative charge and a negligible mass. They are electrons. Hence, - particle is represented as -1 e 0 . They affect photographic plate. They ..

The velocity of a particle is related with its displacement S as V 2 = 9S 2 + 5 k S + k 2 where k is a constant. What is the acceleration of the particle when it is α units away from the starting point? => α units or 9 k units or ( &alpha..

A particle is moving along a straight line so that at time t , its displacement S from a fixed point in the line is given by S = 4 α sin(7 β t + γ) where α , β , γ are constants. If V and f are the velocity and acceleration of the ..
