Physics, Science / By

Two Identical Undamped Oscillators Have The Same Amplitude Of Oscillation Only If: EXPERT ANSWER Yes the correct answer is D when both will have same  Because Amplitude (A) of both will be same when their energies will be same. Hence same amplitude require same energy. So for first oscillator energy will be : Here E1 be …
