What is the ratio of the charges of `alpha` and `beta`- particles?

What are the mass and charge of an alpha -particle?

92^(U^(238)) undergoes a series of changes by emitting alpha and beta particles and finally 82^(Pb^(206)) is formed. Calculate the number of alpha and beta particles emitted during the change.

The ratio of the masses and charges of a proton and an alpha particle are respectiely 1:4 and 1:2 . They enter a uniform magnetic field of magnitude B normally with same kinetic energy. What will be the ratio of the radii of the circular paths described by the particles in each case ?

The ratio of the masses and charges of a proton and an alpha particle are respectively 1:4 and 1:2 . They enter a uniform magnetic field of magnitude B normally with same momentum and What will be the ratio of the radii of the circular paths described by the particles in each case ?

What is mass defect? If _92U^(235) disintegrate to _82Pb^(207) then find the no of alpha and beta particle emitted by it.

In a magnetic field the curvature of the path of a beta - particle is greater than that of a alpha -particle of the same speed. Expalin why.

The ratios of the masses and charges of a proton and an alpha particle are respectiely 1:4 and 1:2 . They enter a uniform magnetic field of magnitude B normally with same velocity. What will be the ratio of the radii of the circular paths described by the particles in each case ?

If sec(alpha-beta)=sqrt(2) and sin(alpha+beta)=(1)/(2) , then find the least positive values of alpha and beta .

State the differences between alpha and beta - particles in respect of their charges , masses and ionisation powers .
