Answer 2

Position vector of P=3 vec a -2 t

Position vector of Q= vec a + vec b

Point R divides segment

PQ in ratio 2:1 externally.

Position vector of R = (Position 1 of P)1-(Position of Q)2 1-2

Position vector of R =; (3 vec a -2 vec b )1-( vec a + vec b )2 1 = vec a -4 vec b -1

Therefore, position vector of R=4 vec b - vec a .
