A) \[\frac{3{{A}_{0}}}{4}\]
B) \[{{A}_{0}}\]
C) \[4{{A}_{0}}\]
D) \[121{{A}_{0}}\]
Correct Answer: A
Solution :
Change in angular momentum \[=4{{A}_{0}}-{{A}_{0}}\] \[\Delta L=3{{A}_{0}}\] Torque, \[\tau =\frac{\Delta L}{\Delta t}\] \[\tau =\frac{3{{A}_{0}}}{4}\]You need to login to perform this action.
