यदि \(\mathop P\limits^ \to = \mathop Q\limits^ \to \) तब निम्न में से कौनसा विकल्प असत्य है
1 \(\hat P = \hat Q\)
2 \(|\,\mathop P\limits^ \to \,|\, = \,|\,\mathop Q\limits^ \to \,|\)
3 \(P\hat Q = Q\hat P\)
4 \(\mathop P\limits^ \to + \mathop Q\limits^ \to = \hat P + \hat Q\)
Explanation:
(d)\(\mathop P\limits^ \to + \mathop Q\limits^ \to = P\hat P + Q\hat Q\)
