A) \[n-p-n\]
B) \[{{K}_{\gamma }}-X-ray\]
C) \[n=4\,to\,n=1\]
D) \[n=3\,to\,n=1\]
Correct Answer: A
Solution :
Key Idea: Law of conservation of energy is valid here. Potential energy is energy result from position or configuration of knife edge, this potential energy is utilized in doing work against resistive force offered by the wood. Hence, potential energy=work done \[Velocity=\left[ L{{T}^{-1}} \right]\] \[\therefore \] \[\Rightarrow \] \[\left[ M \right]=\left[ E\,{{v}^{-2}} \right]\,\] \[K\]You need to login to perform this action.
