Question

A source is moving on a circle of radius 3 m with constant angular velocity ω = 5 r a d s - 1 . If the observer is at a distance 5 m from the centre of the circle, the time interval between the maximum and minimum frequency received by the observer is, π 5, 2 5 cos - 1 ⁡ 3 4, 2 5 cos - 1 ⁡ 3 5, 2 5 sin - 1 ⁡ 3 5

MARKS App · Accepted Answer

When the source is at point P , the frequency received is minimum and when the source is at point Q , the frequency received is maximum. 2 θ = ω t t = 2 5 cos - 1 ⁡ 3 5
