A) \[\sqrt{13}\]
B) \[\sqrt{15}\]
C) \[\sqrt{17}\]
D) 4
Correct Answer: B
Solution :
As for SHM, first, \[{{A}_{1}}=40\] units And for the second SHM \[{{A}_{2}}=\sqrt{100+100\,{{C}^{2}}}\] \[=10\sqrt{1+{{C}^{2}}}\] As per question, \[{{A}_{1}}={{A}_{2}}\] \[\Rightarrow \] \[40=10\sqrt{1+{{C}^{2}}}\] \[C=\sqrt{15}\]You need to login to perform this action.
