Q11. Six simple harmonic oscillations each of same frequency and equal amplitude are superposed. The phase difference between any two consecutive oscillations 1.e., On -1= A is constant, where ó, is the phase of the n" oscillation. If the resultant amplitude of the superposition is zero, what is the phase difference Ad ? (a) (b) (c) 2 (d) 27
