Question

The resultant of two forces acting at an angle of
150° is 10 kgwt, and is perpendicular to one of the
forces. The magnitude of smaller force is
(103 kgwt (2) 20-13 kgwt
(3) 20 kgwt (4) 10 kgwt​

Answer 1

The green vector is the smaller one

The blue vector is the resultant of red and green and has magnitude 10kgwt. = 98N

As the angle between green & blue must be 60°
