The sum of three vectors shown in figure...

The sum of three vectors shown in figure, is zero.
(i) What is the magnitude of vector `vec(OB)` ?

(ii) What is the magnitude of vector `vec(OC)` ?

Text Solution

Verified by Experts

The correct Answer is:
10 N
Resolve `vec(OC)` into two rectangular components.
`OB=OCcos45^(@) and OA=OCsin45^(@)`
implies `OC=(10)/(sin45^(@))=10sqrt(2)NimpliesOB=(10sqrt(2))((1)/(sqrt(2)))=10N`
