Question A source and an observer moves away from each other, with a velocity of \( 15 \mathrm{~m} / \mathrm{sec} \) with respect to ground. If observer finds the frequency of sound coming from source as \( 1950 \mathrm{~Hz} \). Then actual frequency of source will be (velocity of sound \( =340 \mathrm{~m} / \mathrm{sec} \).) :
(A) \( 1785 \mathrm{~Hz} \)
(B) \( 1968 \mathrm{~Hz} \)
(C) \( 1950 \mathrm{~Hz} \)
(D) \( 2130 \mathrm{~Hz} \)📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
