Class XI Multiplying a vector v⃗ v→ by a negative real number λ gives a vector v′→v′→ = λv⃗ λv→ in a direction opposite to v⃗ gives a vector v′→v′→ = λv⃗ λv→ in the same direction as v⃗ gives a scalar that is λλ times the magnitude of v⃗ gives a scalar that is λλ times the polar angle of v⃗ The addition of vectors and the multiplication of a vector by a scalar together gives rise to asymmetric laws intransitive law distributive laws commutative law Two vectors are equal if the two vectors have opposite directions the direction is the same for both the magnitude is the same for both the magnitude and direction are the same for both If are x, y and z components of a vector then its magnitude is Clear Ax, Ay and Az A2 + + x A2y A2z −−−−−−−−−−− A2 +2 + x A2y A2z −−−−−−−−−−−− √ A2 -2 + x A2y A2z −−−−−−−−−−−− √ A2 +3+ x A2y A2z −−−−−−−−−−−− √ A unit vector is a vector having a magnitude of 1 and points in x-direction having a magnitude of 1 and points in y-direction having a magnitude f 1 ando points in any chosen direction having a magnitude of 1 and points in z-direction Do you really want to submit this quiz?
