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.

Its SI unit is Nm. The dimension of the torque is ML²T-2. Angular Momentum. Torque and angular momentum are closely related to each other. Angular momentum is the rotational analogue of linear momentum ‘p’ and is denoted by ‘l’. It is a vector product. Angular momentum of the particle is. l = r × p
Angular velocity is the rate of velocity at which an object or a particle is rotating around a center or a specific point in a given time period. It is also known as rotational velocity. Angular velocity is measured in angle per unit time or radians per second (rad/s). The rate of change of angular velocity is angular acceleration.
The orbital angular momentum and angular momentum (classical analogue) for the electron of 4s -orbital are respectively, equal to: View Solution. Q 5.

Define Torque and angular momentum. Mention their units. Give the relation between them. The turning effect of a force is called Torque. The angular momentum of the body is defined as the moment of momentum about the axis of rotation. The relation between Torque & angular momentum is L = τ ω α. Was this answer helpful?
Correct option is D. Angular momentum. The unit of the Planck's constant is J ⋅ s.
Angular momentum. B. Momentum. C. Velocity. ... Dyne is the CGS unit of work while newton is the SI unit ...
Joule is a unit of energy and second is the unit of time. Thus, J oule×second has dimensions M L2T −2 ×T =M L2T −1. Now, energy cannot be the answer since energy has Joule as its unit and cannot be Joule-seconds. Momentum can't be the answer as momentum is force X time which has dimensions M LT −1. Angular momentum is given by cross ...
