If we assume that penetrating power of any radiation/ particle is inversely proportional to its de‐Broglie wavelength of the particle then:
A
A proton and an 
‐pa1ticle after getting accelerated through same potential difference will have equal penetrating power.
‐pa1ticle after getting accelerated through same potential difference will have equal penetrating power.
B
Penetrating power of 
‐particle will be greater than that of proton which have been accelerated by same potential difference.
‐particle will be greater than that of proton which have been accelerated by same potential difference.
C
Proton’s penetrating power will be less than penetrating power of an electron which has been accelerated by the same potential difference.
D
Penetrating powers cannot be compared as all these are particles having no wavelength or wave nature.
Text Solution
Verified by ExpertsThe correct answer is:
B
For higher 
and 
will be smaller.
For an 
particle, both ’m’ and ’q’ are higher.
Hence, lesser is the wavelength.
As, 
penetrating power) 
Energy 
From above, penetrating power of an 
‐particle is more than that of a proton.
