A) \[5\times {{10}^{-12}}\]
B) \[6\times {{10}^{-13}}\]
C) \[3\times {{10}^{-12}}\]
D) \[5\times {{10}^{-13}}\]
Correct Answer: B
Solution :
(i) The collision is said to be elastic when the kinetic energy is conserved. (ii) Linear momentum is conserved in all types of collision (iii) Angular momentum of a system remain constant if resultant torque acting on it is equal to zero. As \[L=I\omega ,\]so if \[\vec{\tau }=0\]then \[I\omega =cons\tan t\] (iv) In all physical process the total energy is conserved. So, option is correct.You need to login to perform this action.
