A vector f1 is along the positive x axis


Asked by admin @ in Physics viewed by 292 People


A vector F1 is along the positive X-axis. If it's vector product with another vector F2 is zero then F2 vector maybe:- (1)4j cap (2)-(icap+jcap) (3)(icap+kcap) (4)-4jcap

Answered by admin @



Explanation:

As vector F1 is along then its value can be written as ki

and

f1 \times f2 = 0

so

f2 may be in x direction

so they are on same axis so F2 =-4i
