Question

let A=2i-3j+4k and B=4i+j+2k then (A*B) is equal to
​

Answer 1

Answer:ab

Explanation:

Answer 2

Answer:

The cross product of A and B is (-10i+12j+14k).

Explanation:

Given that,

$A =2i-3j+4k$

$B=4i+j+2k$

We need to calculate the cross product

Using formula of cross product

$A\timesB=(2i-3j+4k)\times(4i+j+2k)$

$A\timesB=i(-6-4)-j(4-16)+k(2+12)$

$A\timesB=-10i+12j+14k$

Hence, The cross product of A and B is equal to (-10i+12j+14k).
