Question

Select One Option Correct from the following : Function $x = A \sin^{2} \omega t + B \cos^{2} \omega t + C \sin \omega t \cos \omega t$represents SHM,
(A)For any value of A, B and C (except C = 0) .
(B)If A = −B, C = 2B, amplitude = $|B \sqrt{2} |$ .
(C)If A = B, C = 0
(D)If A = B, C = 2B, amplitude = $|B|$.

Answer 1

c option is correct I think

Answer 2

Select One Option Correct from the following : Function $x = A \sin^{2} \omega t + B \cos^{2} \omega t + C \sin \omega t \cos \omega t$represents SHM,

(A)For any value of A, B and C (except C = 0) .

(B)If A = −B, C = 2B, amplitude = $|B \sqrt{2} |$ .

✴️ (C)If A = B, C = 0

(D)If A = B, C = 2B, amplitude = $|B|$.
