Q. Angular momentum of the particle rotating with a central force is constant due to
AIEEE
AIEEE 2007
System of Particles and Rotational Motion
A
constant torque
27%
B
constant force
12%
C
constant linear momentum
23%
D
zero torque
38%
Solution:
Torque due to central force is zero.
As $\tau=\frac{dL}{dt}=0$
$\therefore L =$ constant
