Three particles start from the origin at the same time, one with velocity `u_1` along the x-axis, the second with velocity `u_2` along the y-axis . Find the velocity of the third particles, along the x=y line so that the three particles may always lie on the same straight line.

Three particles starts from origin at the same time with a velocity 2 ms^-1 along positive x-axis, the second with a velocity 6 ms^-1 along negative y-axis, Find the velocity of the third particle along x = y line so that the three particles may always lie in a straight line.

Three particles starts from origin at the same time with a velocity 2 ms^-1 along positive x-axis, the second with a velocity 6 ms^-1 along negative y-axis, Find the velocity of the third particle along x = y line so that the three particles may always lie in a straight line.

Three particles starts from origin at the same time with a velocity 2 ms^-1 along positive x-axis, the second with a velocity 6 ms^-1 along negative y-axis, Find the velocity of the third particle along x = y line so that the three particles may always lie in a straight line.

Three particles start from the origin at the same time, one with a velocity v_(1) along the x-axis, second along the 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:

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:

Three particles A,B and C start from the origin at the same time, A with a velocity a along x -axis, B with a velocity b along y -axis and C with velocity c in XY plane along the line x=y .The magnitude of c so that the three always remain collinear is:

Three particles start from origin at the same time: one with velocity v^(1) along positive x-axis, the second along the positive y-axis with a velocity v^(2) and the third along the line y = x with such a speed that all the three always stay in a straight line, then velocity of the third particles is:
