The angle between `(vecAxxvecB)` and `(vecBxxvecA)` is (in radian)

A

In x-y plane

B

In y-z plane

C

In x-z plane

D

Along x-axis

Text Solution

Verified by Experts

The correct Answer is:
B

`vec(F)_(1)+vec(F)_(2)+vec(F)_(3)+vec(F)_(4)`
`=(4hat(i)-5hat(j)+5hat(k))+(-5hati+8hatj+6hatk)+(-3hati+4hatj-7hatk)+(12hati-3hatj-2hatk)=4hatj+2hatk`
`rArr` motion will be in y-z plane
