Position of a particle in a rectangular -co-ordinate (3,2,5) . Then its position vector will be

Position of a particle in a rectangular -co-ordinate (3,2,5) . Then its position vector will be

Assertion (A) : The position of a particle on a rectangular coordinate system is (3,2,5). Then its position vector be 2hat(i)+5hat(j)+3hat(k) . Reason (R ) : The displacement vector of the particle that moves from point P(2,3,5) to point Q(3,4,5) is hat(i)+hat(j) .
