Two cars `A` and `B` moving on two straight tracks inclined at an angle `60^(@)` heading towards the crossing initially their positions are as shown in the figure. Both cars have same speed. Minimum seperation between them during their motion will be.

A

`10km`

B

`5sqrt(3)km`

C

`5km`

D

`(20)/(sqrt(3))km`

Text Solution

Verified by Experts

The correct Answer is:
B
Let consider `B` as oberver
`d_("min")=10 sin 60 km=5sqrt(3)`

A square ground of side a = 10/sqrt2 m has a circular running track of radius a/2 with its centre coinciding the centre of the ground. A man is running on the track with an angular velocity omega = 22 rad /s while a car is moving on a road adjacent to ground as shown in the figure. The car moves in such away that the car, the man and the centre of the ground always lie on the same straight line. If a source of sound of frequency v = 300 Hz is being placed at the centre of the ground find the minimum frequency received by the man in the car. Assume velocity of sound in air is v = 330 m/s.
