Three particles start from the origin at the same time, one with a velocity v 1 along the x -axis, second along the negative y -axis with a velocity v 2 and third particle moves along the line x = y . The velocity of third particle, so that three may always lie on the same line is :

Question

Three particles start from the origin at the same time, one with a velocity v 1 along the x -axis, second along the negative y -axis with a velocity v 2 and third particle moves along the line x = y . The velocity of third particle, so that three may always lie on the same line is :, v 1 + v 2 2, v 1 + v 2, v 1 v 2 v 1 + v 2, v = 2 v 1 v 2 v 2 - v 1

Slope of AC line = Slope of BA line vt 2 - 0 vt 2 - v 1 t = 0 - - v 2 t v 1 t - 0 v = 2 v 1 v 2 v 2 - v 1
