Question

If a = 2i - 3j - k and b = i + 4j - 2k, then vector a x b is

A. 10\(\hat i\) + 2\(\hat j\) + 11\(\hat k\)

B. 10\(\hat i\) + 3\(\hat j\)+ 11\(\hat k\)

C. 10\(\hat i\) - 3\(\hat j\) + 11\(\hat k\)

D. 10\(\hat i\) - 2\(\hat j\) - 10\(\hat k\)

Answer 1

Correct option is B.10\(\hat i\) + 3\(\hat j\)+ 11\(\hat k\)
