Question

value of cross product of vector Ā with itself(Ā×Ā) is a)1
b)-1
c)0
d)lies between -2 and 1​

Answer 1

Answer:

1

Explanation:

because in cross product value of ACross A is 1 it mean same value cross with same then it 1

Answer 2

Answer:

The correct answer is option (c)

Explanation:

Given,

A vector Ā

Required to find,

The cross product of vector Ā to itself(Ā×Ā)

Recall the formula,

The cross product of two vectors is given by the formula

A × B = |A| |B| sin θ, -------------(1)

θ is the angle between A and B

Here,

θ is the angle between A and A

θ  = 0

Sin θ  = Sin 0 = 0

Hence, From equation(1),

A × A = |A| |A| sin 0 = 0

The cross product of vector Ā with itself (Ā×Ā) = 0

∴ The correct answer is option (c)
