Mark correct statement(s) for vec(a) , ...

Mark correct statement(s) for `vec(a) , vec(b)` and `vec(c)` shown in above diagram :

A

`-vec(a)-vec(b)=vec(c)`

B

`vec(a)+vec(c)=vec(-b)`

C

`vec(a)+vec(c)=vec(b)`

D

`vec(b)-vec(c)=vec(-a)`

Text Solution

Verified by Experts

The correct Answer is:
B, D
From triangle law :m
` " "vec(a)+vec(b)=-vec(c)`
`rArr " " -vec(a)-vec(b)= vec(c)" " "Hence(A)" `
`rArr " " vec(a)=vec(c)=-vec(b) " " "Hence (B)" `
`rArr " " vec(b)+vec(c)=-vec(a) " " "Hence (D)`
