Answer:
Step-by-step explanation:
From the question, given that,
To find the , let's assume that,
Therefore, we will get the dot product as,
Also, finding the cross product, we get,
But, we know that,
Therefore, we will get,
Comparing the coefficient, we have,
From eqn (2)and (3), we have,
Now, substituting these values in eqn (1), we get,
Therefore, we will get,
and,
Hence, we get the required vector,
