Two horses pull horizontally on  ropes attached to a stump.The  two forces F and T that they  applied to the stump are such that  the resultant R has a magnitude  equal to F and makes an angle of  90° with F.Let F=1300N and   R=1300N.Find the value of T.

T=1300×(√2)    as vector  R=F+T  1300j=1300i+T  ⇒T=−1300i+1300j  T=1300(√2)
T=1300×2asvectorR=F+T1300j=1300i+TT=1300i+1300jT=13002
