Answer:
Explanation: Decreasing in velocity
Explanation:
It is given that,
Uncertainty in the speed of an electron, 
According to Heisenberg uncertainty principle,

is the uncertainty in the position of an electron
Since, 



So, the uncertainty in its position is
. Hence, this is the required solution.
It would be: 40 + 272 = 313 K
In short, Your Answer would be Option A
