[" 4.यदि Linear "PQ" On "R" Is a point so that "],[PR:RQ=2:3" Jabaki "P=(5,2,-6)],[" And "Q=(1,0,-3)," so "R" Is the regulator of "]

If the points P (1,2,3), Q(4,5,6) and R(7,8,9) are collinear then Q divides PR in the ratios of -

Show that the points P(0,2) Q(3,-1) R(-2,-6) and S(-5,-3) are the verties of a rectangle.

Show that the points P(0,2) Q(3,-1) R(-2,-6) and S(-5,-3) are the vertices of a rectangle.

Draw a line segment PQ=8cm. Take point R on it such that l(PR):l(RQ)=3:2 .

The ends of a line segment are P(1, 3) and Q(1,1) , R is a point on the line segment PQ such that PR : QR=1:lambda .If R is an interior point of the parabola y^2=4x then

Draw a line segment PQ=8 cm.Take a point R on it such that l(PR):l(RQ)=3:2.

The position vectors of P and Q are respectively a and b. If R is a point on PQ such that PR=5PQ, then the position vector of R is
