If vec(tau)xxvec(L)=0 for a rigid body, ...

If `vec(tau)xxvec(L)=0` for a rigid body, where `vec(tau)=` resultant torque & `vec(L)` =angular momentum about a point and both are non-zero. Then

A

`vec(L)=`constant

B

`|vec(L)|`=constant

C

`|vec(L)|` will increases

D

`|vec(L)|` may increase

Text Solution

Verified by Experts

The correct Answer is:
D
`sin theta=0` so `theta=0, pi`
In case of `theta=0, vec(L)` will increases

The correct relation between torwue tau and angular momentum L is

Torque (vec tau) acting on a rigid body is defined as vec tau = vec A xx vec L , where vec A is a constant vector and vec L is angular momentum of the body. The magnitude of the angular momentum of the body remains same. vec tau is perpendicular to vec L and hence torque does not deliver any power to the body.

The torque vec tau on a body about a given point is found to be equal to vec A xx vec L where vec A is a constant vector and vec L is the angular momentum of the body about the point. From this its follows that -

If the resultant external torque acting on a body is zero, then angular momentum of the body

The relation between the torque tau and angular momentum L of a body of moment of inertia I rotating with angular velocity omega is

Two particle are initially moving with angular momentum vec(L)_(1) and vec(L)_(2) in a region of space with no external torque. A constant external torque vec( tau) then acts on one particle, but not on the other particle, for a time interval Delta t . What is the chargne in the total angular momentum of the two particles ?

If vec a xxvec b = vec c, vec b xxvec c = vec a, where vec c! = 0

The torque tau on a body about a given point is found to be equal to A x L, where A is constant vector and L is the angular momentum of the body that point. From this, it follows that

Figure shows a rigid body that is mirror symmetric about a plane and rotates about an axis perpendicular to that plane. Statement-1: Angular momentum of above mentioned rigid body can be expressed by vec(L)=vec(Iomega) where I is moment of inertia about rotation axis. Statement-2: vec_(L)=I vec(omega) can be applied only for those rigid bodies that have rotational symmetry about an axis and rotate about that symmetry axis.

Suppose, the torque acting on a body, is given by tau = KL+(MI)/(omega) where L = angular momentum, l = moment of inertia & omega = angular speed. What is the dimensional formula for KM?
