No its more complicated than that. Use Cartesian coordinates withsapplesapple said:I find 2ihp, is that correct? do you know the correct answer?
A commutator in computing refers to an operation that calculates the difference between two quantities and is denoted by [A,B]. In this case, [L,p] represents the commutator between the angular momentum operator (L) and the momentum operator (p).
The commutator [L,p] is used to determine the uncertainty in the measurement of angular momentum and momentum. It helps in understanding the relationship between these two physical quantities and their corresponding operators.
To compute the commutator [L,p], you can use the formula [L,p] = Lp - pL, where L and p are operators. First, calculate the product of L and p, then calculate the product of p and L, and finally subtract the second product from the first product.
The commutator [L,p] has the following properties:
In quantum mechanics, the commutator [L,p] is used to calculate the uncertainty in the measurement of angular momentum and momentum for a quantum system. It also helps in determining the compatibility of two physical quantities, where the commutator is non-zero if the two quantities are not compatible.
