Three points A, B, C are located in a straight line AB=a and AC=b.Two particles start from points B and C and move with uniform velocities v_(1) and v_(2)respectively such that angle between vec(v_(1)) and line ABC and vec(v_(2)) and ABC is theta. If point A and both the particles are always in a straight line then the relation between a, b, V_(1), V_(2) is aV_(2)= kb V_(1). The value of 'k' is

1.	Three points A, B, C are located in a straight line AB=a and AC=b.Two particles start from points B and C and move with uniform velocities v_(1) and v_(2)respectively such that angle between vec(v_(1)) and line ABC and vec(v_(2)) and ABC is theta. If point A and both the particles are always in a straight line then the relation between a, b, V_(1), V_(2) is aV_(2)= kb V_(1). The value of 'k' is
