A RARELY SEEN VECTOR METHOD AND DON'T MISS THE IMPORTANT PRACTICE PROBLEMS GIVEN AT THE END 
Q : Two identical elastic cords of negligible relaxed lengths are tied at one of their ends to fixed nails A and B that are equidistant from the origin O. The other ends of the strings are tied to a small ball. To hold the ball in equilibrium at a point P (4 m, 3 m), a force of magnitude F = 1000 N is required. Assuming free space conditions, find force constant of the cords?
