The resultant of two forces 1 and P is perpendicular to 1 and equal to 1 What is the value of p


Resultant is 1. One force is also1. They are perpendicular to each other. This implies angle between p and the 1 force is more than 90. Let us say it is 90 + a.

Resolving p , the one parallel to the 1 force is p sin a, the perpendicular one is p cos a.

Hence both are equal to one.

tan a = 1 hence a = 45. And p = Root of ( 1+1) = root 2.
