Gold foil used in Geiger-Marsden experiment as about 
thick. This ensures
A
gold foil's gravitational pull is small as possible
B
gold foil is deflected when 
-particle stream is not incident centrally over it
-particle stream is not incident centrally over it C
gold foil provides no resistance to passage of 
-particles
-particles D
most 
-particle will not suffer more than 
scattering during passage through gold foil
-particle will not suffer more than scattering during passage through gold foil
Text Solution
Verified by ExpertsThe correct answer is:
D
As the gold foil is very thin, it can be assumed that 
-particles will suffer not more than 
scattering during their passage through it. Therefore, computation of the trajectory of an 
-particle scattered by a single nucleus is enough.
