Question

If two vectors point in opposite directions, their cross product must be zero.

True False

Answer 1

Answer:

True

Explanation:

Because AxB=lAllBlsin(x)

and x is the angle between them

so, the angle is 180° and sin180 is zero.

Answer 2

In the case when the two vectors point in opposite directions so there cross product should be zero.

Impact on two points:

In the case when the two vectors point in opposite directions so there cross product should be zero.

Like

A*B = [A][B] sin$\theta$

Here theta is be the angle that lies between them

So,

A*B = [A][B] sin 180

So, A*B = 0

hence, the given statement is true.
