Class XII Coinitial Vectors are Two or more vectors having the same final point Two or more vectors having the same initial point Two or more force vectors having the same initial point Two or more pseudo vectors having the same initial point Zero Vector A vector whose initial and terminal points coincide A vector whose initial and final points are different A vector whose terminal points are at origin A vector whose initial points are at origin Unit Vector is A vector whose direction angle α is unity A vector whose direction angle γ is unity A vector whose direction angle β is unity A vector whose magnitude is unity If l, m and n are direction cosines of the position vector OP the coordinates of P are lr, mr and nr lr, mr and n lr, m and nr l, mr and nr Vectors A and B are equal if they have the same magnitude if they have the same magnitude and direction if they have the same magnitude and opposite direction if they have the same direction Do you really want to submit this quiz?
