What is the significance of the expectation value of momentum being zero in quantum mechanics?

In quantum mechanics, the expectation value of momentum being zero signifies that there is no preferred direction of motion for a particle. This implies that the particle is equally likely to be found moving in any direction, reflecting the inherent uncertainty and probabilistic nature of quantum systems.


Why does expectation value of momentum of a particle in one dimensional box box for state one comes to be zero?

Recall that, in basic quantum mechanics, the "expectation value" of a quantity is the arithmetical mean you would get if you measured that quantity innumerable times. A particle in a one-dimensional box is basically bouncing back and forth within the box, with no change in momentum between bounces. Thus, it is just likely to have momentum in one direction (let's call it "to the left") as the other direction ("to the right"). If you take several measurements of the momentum, half will have a leftward momentum, half will have a rightward momentum -- and the size of all measurements will be equal (no loss of velocity in the bounce). If you sum up all such measurements, the half going left will thus exactly cancel the other half going right. Since the sum is zero, the arithmetic mean is zero, and thus the expectation value is zero.

What is the probability that a gaussian probability density function will take a value less than -2?

Assuming that you are considering a N(0,1) Gaussian distribution, the answer is approximately 1 in 20. The 0.95%ile (two tailed) occurs at -1.96 and 1.96.
