AIIMS Full Mock Test 8 - Question 4

An electron and a proton have same de-Broglie's wavelength. The kinetic energy of an electron is

Detailed Solution for AIIMS Full Mock Test 8 - Question 4
As electron and proton have same de Broglie wavelength then the electron must have more more velocity as compared to proton because there momentum will be same Nd mass of proton is greater than mass of electron so.....we know k.E =1/2mv^2 or 1/2(momentum)*v....hence velocity of electron will be more that proton so...k.Eof electron will be more than proton...
AIIMS Full Mock Test 8 - Question 5

AIIMS Full Mock Test 8 - Question 7

A particle of mass m at rest decays into two masses m₁ and m₂ with non-zero velocities. The ratio of de-Broglie wavelengths of the masses λ₁/λ₂ is

Detailed Solution for AIIMS Full Mock Test 8 - Question 7
De broglie wave length is given by λ=h/p
where h is planks constant and p is  momentum. 
Now the mass M was at rest initially so from the momentum conservation 
we can write that 
p1=p2
Since the momentum is equal, the de broglie wavelength will be equal.
Hence answer (A) is corect option.

AIIMS Full Mock Test 8 - Question 23

A cube is subjected to a uniform volumatric compression. If side of cube decreases by 1%, then its bulk strain is

Detailed Solution for AIIMS Full Mock Test 8 - Question 23
The answer should be 0.03.as per the question side of cube decreased by 1% or by 0.01.since we know bulk strain=change in volume divided by original volume. as volume of cube =cube of side of square. hence bulk strain=change in volume by original volume = 3*(change in side by original side) =0.03
