Plzzz Answers kardo her with full explanation ✨✨✨ Three particles A B and C are situated at vertices of an equilateral triangle ABC of side B at t = 2 0. each of the particle moves with a constant speed v. a always has its velocity along a b, b along b c and C along CA. at what time will the particle meet each other |
|
Answer» e at which the three particles meet each other is equal to the time at which any of the particle reaches O. From the fig., we get the time of meeting is equal to the time during which the particle at B MOVES TOWARDS O. The particle has a velocity COMPONENT along OB.Let be the length of each SIDE of the equilateral triangle. Then the time of meeting is,But from ΔOBD,Then (1) becomes, |
