Assertion: For the scattering of alpha -particles at a large angles, only the nucleus of the atom is responsible. Reason: Nucleus is very heavy in comparison to electrons.
Can a triangle have two rght angles? two abtuse angles? two acute angles? all angles more than 60^(@) all angles less than 60^(@)? all angles to 60^(@) ?
Is it possible to have triangle,in which Two of the angles are right? Two of the angles are obtuse? Two of the angles are acute? Each angle is less than 60^(@)? Each angle is greater than 60^(@)? Each angle is equal to 60^(@)? Give reason in support of your answer in each case.
For scattering of alpha -particles at large angles, only the nucleus of the atom is responsible, explain why?
In an alpha -particle scattering experiment , 100 particles are scattered per minute at an angle of 60^@ . Calculate the number of particles per minute scattered at an angle of 30^@
In Rutherford scattering experiment, alpha -particles scattered at angle theta by a target, then which of the following is correct for Impact parameter "b" ?
Obtuse angle an angle whose measure is more than 90^(@) but less than 180^(@) is called an obtuse angle (Fig.11.27) .
In scattering experiment , the force that scatters particles is
If in Rutherford's experiment, the number of particles scattered at 90^(@) angle are 28 per min, then number of scattered particles at an angle 60^(@) and 120^(@) will be
In Rutherford's scattering experiment , 60 particles were scattered per min for theta_1 = 90^@ . How many particles will be scattered per min for theta_2 = 60^@ ?
