Momentum and CollisionHard

Question

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

Options

A.- 3 √3
B.3√3
C.- 3√2
D.2√2

Solution


Co - ording of P
∴ Speed of 3rd particle = 3√2 m/s
