Consider the given scenario in which block, block is suspended, scenario in which a block is suspended with the help of a string. The mass of the block is 10 kg. Listen carefully, this 10 kg block will experience a downward force due to the gravity, I think we all know that. So there will […]
Std 11, Vectors, 07 cross product, continued
Let us take one more example on cross product. Write down the problem, find the value of A cross B if A and B vectors are together, if we already know A and B vector then lets us find the value of A cross B. okay. Let’s […]
In last lecture we were dealing, we were discussing about the position vectors. Let us consider a point at certain coordinates x, y and z. And then the position of A point with respect to origin is defined as x coordinate i cap, y coordinate j cap and z coordinate k cap. This is position […]
So far, okay, so far we have discussed the addition and subtraction of two vectors. Now let’s see one more mathematical operation which is very much important for the understanding of various aspects of physics and that is the product of two vectors. So let us discuss the product of two vectors.
Depending upon the end […]
Let us consider a vector a. let’s say this is a vector a. Then what is the meaning of vector minus a. minus a that means a vector is multiplied by minus one. That means the vector is rotated by an angle of 180 degrees. So if a vector is multiplied by minus one that […]
Addition of two vectors. Case one. Case one. If we have magnitudes of two vectors. Magnitude of two vectors and angle between them. So we are planning to work out the addition or we are planning to work out about the resultant force, resultant vector in fact, if you know the magnitude of two vectors […]
Find the angle between given vector with the help of given angle. Not visible. Ok I will redraw the figure for you. Three vectors, we need to find angle between PQ, QR and PR. If I have given you some example 45, 45 and this angle 90 deg.
Tell me what is the angle between P […]
We will start with the vector. Note down the definition of the Vector
A physical quantity is said to be vector quantity if it carries direction as well as magnitude and it follows Triangle law of vector addition.
See when it comes to the understanding of vector, the definition includes 3 important aspects.
First, direction, quantity should carry […]
