Question

if vector A = 2i +3j -k and vector B = -4i -6 j -xk are parallel find the value of x​

Answer 1

Step-by-step explanation:

since vectorA and vector B are parallel to each

other then their scaler product should

not be equal to zero.

condition=> A= kB => A/B = k

where k= constant

=> -1/-x= 2/-4= -1/2

=> 1/x= -1/2

x= -2
