Solve the following:find the equation of the circle which passes through the points (1,-2),(4,-3) and whose centre lies on the line 3x+4y=7

A roller is made by joining together two cones at their vertices O, ti is kept on two rails AB and CD, which are placed asymmetrically with its axis perpendiuclar to CD and its center O at the centre of line joining AB and Cd it is given a light push so that it starts rolling with its centre O moving parallel to CD in the direction shown As it moves, the roller wil tand to:

Choose the correct alternative.The equation of the circle which passes through the points (2,3) and (4,5) and the centre lies on the straight line y-4x+3=0 is

The radii of a planet and its satellite are 2r and r and their densities are rho and 2rho respectively. Their centres are separated by a distance d. The minimum speed with which a body should be projected from the mid point of the line joining their centres so that the body escapes to infinity is (G-universal gravitational constant)
