When a gold sheet is bombarded by a beam...

When a gold sheet is bombarded by a beam of `alpha-` particles, only a few of them get deflected, whereas most go straight, undeflected. This is because:

A

the force of attraction on `alpha`-particles by the oppositely charged electron is not sufficent

B

the nucleus occupies much smaller volume as compared to the volume of atom

C

the force of repulsion on fast moving `alpha`-particles is very small

D

the neutrons in the nucleus do not have any effect on `alpha`-particles

Text Solution

Verified by Experts

The correct Answer is:
B
Most of the space in an atom in empty i.e., vacuum and the volume occupied by nucleus is much small `(10^(-15)m)` as compared to size to atom `(10^(-10)m)`.

In the gold foil experiment of Geiger and Marsden, that paved the way for Rutherford's model of an atom, ~ 1.00% of the alpha -particles were found to deflect at angles gt 50^(@) . If one mole of alpha -particles were bombarded on the gold foil, compute the number of alpha -particles that would deflect at angles less than 50^(@) .

Following experiment was performed by J.J. Thomson in order to measure ratio of charge e and mass m of electron. Electrons emitted from a hot filament are accelerated by a potential difference V. As the electrons pass through deflecting plates, they encounter both electric and magnetic fields. the entire region in which electrons leave the plates they enters a field free region that extends to fluorescent screen. The entire region in which electrons travel is evacuated. Firstly, electric and magnetic fields were made zero and position of undeflected electron beam on the screen was noted. The electric field was turned on and resulting deflection was noted. Deflection is given by d_(1) = (eEL^(2))/(2mV^(2)) where L = length of deflecting plate and v = speed of electron. In second part of experiment, magnetic field was adjusted so as to exactly cancel the electric force leaving the electron beam undeflected. This gives eE = evB. Using expression for d_(1) we can find out (e)/(m) = (2d_(1)E)/(B^(2)L^(2)) If the electron is deflected downward when only electric field is turned on, in what direction do the electric and magnetic fields point in second part of experiment
