A) 2 J
B) 4 J
C) J/2
D) J/4
Correct Answer: D
Solution :
Rotational kinetic energy, \[5.26\times {{10}^{3}}\] Angular momentum \[({{R}_{e}}=6.37\times {{10}^{6}}m)\] \[mg{{R}_{e}}\,.\] \[{{R}_{e}}\] \[{{R}_{e}}\] \[-2mg{{R}_{e}}\] \[2mg{{R}_{e}}\] \[1\frac{1}{2}mg{{R}_{e}}\]You need to login to perform this action.
