A vector F1 is along +ive x axis it's cross product with another vector is possibly equal to
A.3i+5k
B.-3(j+k)
C.2j
D.5i

Answer: B.
Explanation:
Since it is given along positive x axis j and I components are 0 so their cross product with another vector gives only j and I components....
k* components( typo)
What option would you choose?
B is not right one it's C in answer key
But if u take an example and try it you'll get it something in j and k components right......
So then can you explain it on a page like what you're saying
And it's not k comp what we get is only j comp
It is given that the vector F1is along x axis implies j and k components are 0 so when u cross product with an other vector you'll probably end up with j and k components itself.......
Okay
