What is the magnitude of two vectors perpendicular to each other?
The magnitude of scalar product of two unit vectors perpendicular to each other is zero.
At what angle is the magnitude of two vectors maximum?
0
Hint: The maximum resultant of 2 vectors is when the angle between them is 0 and the minimum resultant is when the angle between them is 180.
Is the sum of two unit vectors is a unit vector then the magnitude of the difference is?
√2.
How do you find the magnitude and direction of two vectors?
We find its magnitude using the Pythagorean Theorem or the distance formula, and we find its direction using the inverse tangent function. Given a position vector →v=⟨a,b⟩,the magnitude is found by |v|=√a2+b2. The direction is equal to the angle formed with the x-axis, or with the y-axis, depending on the application.
What is magnitude of a unit?
Units of measure are scalar quantities, and magnitude is defined in terms of scalar multiplication. The magnitude of a quantity in a given unit times that unit is equal to the original quantity. For scalar quantities, one can think of the magnitude as the ratio of a quantity to the unit quantity.
When two vectors A and B are added then maximum value of resultant is?
R is maximum when Cos ( A, B) = +1 ie angle between vectors A and B is zero ie vectors A and B are parallel to each other. The resultant of two vector is minimum when both vectors are equal and in opposite direction i.e. the angle between the vector is 180 degrees.
How do you find the magnitude of 3 unit vectors at 90°?
You simply use the value √2 for two unit vectors at 90°. Just to save your time we avoid going through calculations everytime. Similarly Magnitude of 3 unit vectors is √3 (√ (i)² + (j)²+ (k)²). However the angle between them in such a case can be calculated be Direction Cosines. 8 clever moves when you have $1,000 in the bank.
What is the vector with magnitude 5 2 and direction 225 degrees?
For two vectors of 5N at right angles (0 and 90 degrees) the vector that, when added, gives us zero is the vector ( − 5, − 5) with magnitude 5 2 and direction 225 degrees. If your original vectors are not exactly at 0 and 90 degrees, then add the offset to 225 to get the angle of the resultant vector that fits the question.
Is the angle between two unit vectors always 90 degrees?
No ,it is not necessary that the angle between two unit vectors is always 90 degree . Because unit vector means a vector with unit magnitude ; there is no connection of angle with it . If there are two unit vectors then only thing is that both there magnitude is equal to one .
How do you find the result of two vectors at 120 degrees?
Two vectors at 120 degree produce a vector equal to their magnitude. Let their magnitude be a, Resultant = a = (a 2+a 2+2×a×a×cosθ) = a (2+2cosθ)
