Vector: Section formula for internal division

Vector: Section formula for internal division: (Section formula for internal division) The position vector of the point A is a ⃗ and the position vector of B is b ⃗. The position vector of P which divides AB internally in the ratio of m:n is p ⃗. Prove that p ⃗=(mb ⃗+na ⃗)/(m+n). Vector: Section formula for External Division: https://youtu.be/8xzNltKUpwk
