Question

the resultant of two vectors 1 and p is perpendicular to 1 and equal to 1 what is the value of p and angle between the forces

Answer 1

Answer:

2

Explanation:The resultant of two forces 1 and p is perpendicular to 1 and equal to 1. what is value of p and angle between them?

Resultant is 1. One force is also 1. They are perpendicular to each other. This implies angle between p and the  1  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.
