Fig. 12.8 shows a mixed source R of alpha and beta particles in a thick lead walled container. The particles pass through a magnetic field in a direction perpendicular to the plane of paper inwards as shown by x. (a) Show in the diagram how the particles get affected. (b) Name the law used in part (a).
[Hint : alpha particles will deflect to the left while beta particles to the right]

A charged particle moves through a magnetic field perpendicular to its direction. Then

In scattering experiment , alpha -particles were deflected by

When alpha - particles are passed through a thin foil, then

The diagram in Fig. shows a radioactive source S placed in a thick lead walled container. The radiations given out are allowed to pass through a magnetic field (shown as X) acts perpendicular to the plane of paper inwards. Arrows show the paths of the radiations A, B and C. (a) Name the radiations labelled A, B and C. (b) Explain clearly how you used the diagram to arrive at the answer in part (a).

Source of alpha -particles used in scattering experiment was

A charged particle moves through a magnetic field in a direction perpendicular to it. Then the: (1.)acceleration remain unchanged (2.)velocity remains unchanged (3.)speed of particles remain unchanged (4.)direction of particles remain unchanged

Positively charged particles are projected into a magnetic field. If the direction of the magnetic field is along the direction of motion of the charged particles, the particles get

Why are the alpha particles not used in radio therapy ? [Hint : alpha particles cannot penetrate the human skin]

Two identical particles having the same mass m and charges +q and -q separated by a distance d enter a uniform magnetic field B directed perpendicular to paper inwards with speeds v_1 and v_2 as shown in Fig. 1.139. The particles will not collide if

What are the respective number of alpha and beta -particles emitted in the following radioactive decay?
