Solve this question, the resultant of two force acting at right angle to each other on a body is ten newton. If the angle between the resultant and one of the force is sixty degree, find the force.

Answer 1

Three vectors are shown in Fig. 3-32 (A = 68.0 , B = 50.0°). Their magnitudes are given in arbitrary units. Determine the sum of the three vectors.

Figure 3-32

(a) Give the resultant in terms of components.
Rx =
Ry =

(b) What is the magnitude of the resultant?

What is the resultant's angle above the +x axis?
°

Answer 2

Tow forces whose resultant is 100N are at right angle to each other.if one of them makes an angle of 30 with the resultant def.its magnitude

Answer 3

F = 10*Cos60 = 5 N.

Fr = 100N.[30o].
F = 100*Cos30 = 86.6 N.
