Question

SHM of same amplitude of 20$cm$ with same period along the same line about the same equilibrium position. The maximum distance between the two is 20$cm$ . Their phase difference in radians is :

• A. $\frac{2\pi }{4}$
• B. $\frac{\pi }{3}$
• C. $\frac{\pi }{2}$
• D. $\frac{\pi }{4}$

Answer 1

The correct option is B $\frac{\pi }{3}$

$\begin{array}{c}\sin \theta =\frac{10}{20}=\frac{1}{2}\\ \Rightarrow \theta ={30}^0\\ \Rightarrow 20={60}^0\\ \therefore phasedifference=\frac{\pi }{3}\\ Hence,\\ optionBiscorrectanswer.\end{array}$
