    Uncertainty principle, relating the uncertainty in position to the uncertainty

    solution- [x,p2/2m+V]=1/2m[x, p2]+[x,V];  [x, p2]= xp2 − p2x = xp2 − pxp + pxp − p2x = [x, p]p + p[x, p]. using the equation [x,p]=ih{this is known as canonocal commutation relation}  [x, p2]= ihp + pih = 2ihp. and And [x, V ] = 0, so [x,p2/2m+ V]=1/2m(2ihp) = ihp/m The...
