What are the maximum and minimum resultant of the two forces?
The resultant of a number of forces acting on a body is the vector sum of all the forces acting on the body. The maximum resultant forces is found when all the forces have the same direction (parallel forces). The minimum resultant force is found when forces act in exactly opposite directions (anti-parallel forces).
What is the maximum resultant of two vectors?
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.
What is minimum force?
Those minimum actions, including the use of armed force, sufficient to bring a situation under control or to defend against hostile act or hostile intent.
When two vectors are added together their resultant is a minimum when the angle between them is?
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.
What is the minimum angle between two vectors?
Start with the vectors on top of each other. Drag one around until they are 180\(^{\circ}\) from each other, then keep going. Notice that the angle then gets smaller. The angle that is calculated is always the smallest angle between them, which is always between 0\(^{\circ}\) and 180\(^{\circ}\).
Can the angle between two vectors be undefined?
1 Answer. When one of the two vectors is 0, the angle between them is not defined. If a vector v is non-zero, then the direction of that vector can, in some sense, be represented by the vector v‖v‖, and 0‖0‖ is not defined.
What if the angle between two vectors is 0?
Two vectors are parallel ( i.e. if angle between two vectors is 0 or 180 ) to each other if and only if a x b = 1 as cross product is the sine of angle between two vectors a and b and sine ( 0 ) = 0 or sine (180) = 0.
What is the angle between two vectors called?
The length of a vector is defined as the square root of the dot product of the vector by itself, and the cosine of the (non oriented) angle of two vectors of length one is defined as their dot product.
What is angle between i j and ij vectors?
Answer. The angle is 90 degree.

What is the angle between i +j and I?
The angle between the Vector (ˆi+ˆj) and (ˆj+ˆk) is. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams. One of the forces is of magnitude 20√3N and makes an angle of 30∘ with the resultant.
When unit vector n AI BJ is perpendicular to i j then A and B are?
Answer. if two vectors A and B are perpendicular to each other. it means, dot product of vector A and vector B must be zero.
Which of the following vectors is perpendicular to the vector 4i 3j?
The vector perpendicular to the given vector is 3i + 4j.
What is the unit vector perpendicular to 5j 12k?
Answer. Explanation: First, find a vector ai+bj+ck that is perpendicular to 8i+4j−6k. (Set the dot product of the two equal to 0 and solve. Then divide that vector by its length to make it a unit vector. This unit vector will still be perpendicular to 8i+4j−6k .
How do you find a vector that is perpendicular to another vector?
If two vectors are perpendicular, then their dot-product is equal to zero. The cross-product of two vectors is defined to be A×B = (a2_b3 – a3_b2, a3_b1 – a1_b3, a1_b2 – a2*b1). The cross product of two non-parallel vectors is a vector that is perpendicular to both of them.
Which vector is perpendicular to i j k?
Answer. Explanation: Dot product of perpendicular vectors must be zero.
What is the unit vector perpendicular to the plane of vectors A and B?
