If P, Q, R are 3 points on a line and Q lies between P and R, then prove that PQ=PR+RQ

If a point Q lies between P and R such that PQ = QR , prove that PR = 2 PQ .

If a point Q lies between two points P and R such that PQ = QR, prove that PQ = 1/2 PR.

If P,Q,R are in A.P then Q-P=…..

The coordinates of the points A and B are respectively (-3,2) and (2,3). P and Q are points on the line joining A and B such that AP=PQ. A square PQRS is constructed on PQ as one side, the coordinates of R can be

P and Q are points on the line joining A(-2, 5), B(3, -1) such that AP = PQ = QB. Then the mid point of PQ is

The resultant of two forces P and Q is R If Q is doubled and when Q is reversed R is again doubled. Show that P:Q:R

P and Q are two points on a uniform ring of resistance R. The equivalent resistance between P and Q is

A ball dropped from a point P crosses a point Q in t seconds. The time taken by it to travel from Q to R, if PQ=QR
