Physical meaning of a point and Co-ordinates of a point in space.

Cartesian Co-ordinate of a point

Explain the physical meaning of potential and potential difference. Find a relation for electrostic potential at a point due to a point charge.

The family whose x and y intercepts of a tangent at any point are respectively double of the x and y co-ordinates of that point is

If (cos alpha,cos beta) are the new co-ordinates of a point P when the axes are translated to the point (1,1), then the original coordinates are

Using Lagrange's Mean Value theorem , find the co-ordinates of a point on the curve y = x^(3) at which the tangent drawn is parallel to the chord joining the points (1,1) and (3,27).

The co-ordinate o point b on the numberline is -3 . Find the co-ordinates of the points which are at adistance of 6 units from B.

The base QR of an equilateral triangle PQR lies on X-axis. The co-ordinates of the point Q are (-4,0) and origin is the mid-point of the base. Find the co-ordinates of the points P and R.

The co-ordinates of the mid-point of line joining the points A and B are (2, -3). If the co-ordinates of point A are (-3, 4), then find the co- ordinates of point B.
