सरल आवर्त गति करते किसी कण की गति का वर्णन नीचे दिए गए विस्थापन फलन द्वारा किया गया है,
`x(t)=A cos (omega t+phi)`
यदि कण की आरंभिक ( t = 0 ) स्थिति 1 सेमी तथा उसका आरंभिक वेग `pi` सेमी/सेकण्ड है, तो कण का आयाम तथा आरंभिक कला कोण क्या है ? कण की कोणीय आवृत्ति `pi` प्रति/सेकण्ड है | यदि सरल आवर्त गति का वर्णन करने के लिए कोज्या ( cos ) फलन के स्थान पर हम ज्या ( sin ) फलन चुनें ,` x = b sin ( omega 1 + alphla )`, तो उपरोक्त आरंभिक प्रतिबंधों में कण का आयाम तथा आरंभिक कला कोण क्या होगा ?

A

`pi//4`

B

`pi`

C

`pi//3`

D

`pi//2`

Text Solution

Verified by Experts

The correct Answer is:
D

`Deltaphi=(2pi)/(lambda)xxDeltax`
`=(2pi)/(2pi//k)xxDeltax=kxxDeltax=(pi)/(7)xx3.5impliesDeltaphi=(pi)/(2)`.
