A) k, A and M
B) k, x, M
C) k, A
D) k, x
Correct Answer: C
Solution :
In SHM, the total energy = potential energy + kinetic energy or E = U + K \[=\frac{1}{2}m{{\omega }^{2}}{{x}^{2}}+\frac{1}{2}m{{\omega }^{2}}({{A}^{2}}-{{x}^{2}})\] \[=\frac{1}{2}m{{\omega }^{2}}{{A}^{2}}\] \[=\frac{1}{2}k{{A}^{2}}\] where k = force constant = \[m{{\omega }^{2}}\] Thus, total energy depends on k and A.You need to login to perform this action.
