Question

the sum of two concurrent force P and Q is 500N nad their resultant is 400N .If the resultant is perpendicular to P.find P and Q and angle between P and Q​

Answer 1

Explanation:

The answers are given in the below photos.

Tye angle between them can be easily calculated by using-

R=(P^2+Q^2+2PQcos(theta))^0.5

Since the values are too high I didn't calculated it.

If the answers are not correct don't worry,the process is correct and you will get results by this way only.
