Two particles are initially located at points A and B distant d apart. They start moving at time t=0 such that the velocity vecu of B is always along the horizontal and velocity vecv of A is contiunously aimed at B. At t=0 , vecu is perpendicu lar to vecv The particles will meet after time:

1.	Two particles are initially located at points A and B distant d apart. They start moving at time t=0 such that the velocity vecu of B is always along the horizontal and velocity vecv of A is contiunously aimed at B. At t=0 , vecu is perpendicu lar to vecv The particles will meet after time:
Answer» `(vd)/(V^(2)-U^(2))` `(v^(2)+u^(2))/(ud)` `(v^(2)-u^(2))/(vd)` `(ud)/((v^(2)-u^(2)))` Solution :`t=[(d)/(v_("REL"))]`
