For a single electron s = ± 1 2 but for calculating spin angular momentum of an electron on positive value of s is taken. √ 1 2 ( 1 2 + 1 ) h 2 π = √ 3 2 × ( h 2 π )
Solution: We can find the angular momentum by using the formula, and the moment of inertia of a solid disc (ignoring the hole that is present in the middle). The angular momentum will be: L = I ω. L = (12MR2)ω. So, L = 12(0.0200kg)(0.0600m)2(160.0radians/s) L = 0.00576 kg. m2 /s. The angular momentum of this DVD will be 0.00576 kg. m2 /s.
The minimum angular momentum of an electron with the magnetic quantum numbers -1, 0, +1 is h π.
The total angular momentum of the system is Σ ri × pi. Torque for System of Particles. We know that, dl dt = τ, a total torque of the system will be the summation of each of the particles. Σ dl dt. τ i = r i × F i. Σ = r i × F i. Torque is external as well as internal. τ = τ ext + τ int. τ ext = Σ r i × F iext.
Answer 1: An electron spin refers to a form of angular momentum of electrons. Furthermore, it is a quantum property of electrons and its magnitude happens to be permanent. The spin quantum number provides information about an electron’s unique quantum state. Also, the spins play an important role in quantum mechanics.
Electronic configuration of N-atom (Z=7): E C = 1 s 2 2 s 2 2 p 3 (G S), so it has 3 unpaired electrons and sum of spin quantum number is (3/2). A spin angular momentum, L s = √ s ( s + 1 ) h 2 π , where S = sum of spin Q.N. of all the electrons.
Moment of inertia also known as the angular mass or rotational inertia can be defined w.r.t. rotation axis, as a quantity that decides the amount of torque required for a desired angular acceleration or a property of a body due to which it resists angular acceleration. The formula for the moment of inertia is the “sum of the product of mass ...
