Question

Which statement correctly describes the order of vectors joining two points?

विकल्प

• \[\vec{P_1P_2}=\vec{P_2P_1}\]

• \[\vec{P_1P_2}=-\vec{P_2P_1}\]

• \[\vec{P_1P_2}=\left|\vec{P_2P_1}\right|\]

• \[\vec{P_1P_2}=\vec{P_1P_1}+\vec{P_2P_2}\]

Answer 1

Reversing the initial and terminal points reverses the direction of the vector. Hence, the vector in the reverse order is the negative of the original vector.
