what is the dot product and cross product of of two vectors if the angle is between them is 90 degree?

⚡ Let and are the two vectors .

✍️ We have know that,

Where,

[1] The dot product of two vectors is “ 0 ” .

✍️ We have know that,

Where,

[2] The cross product of two vectors is “ ab ” .

true is the correct answer

hope i

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
