Two heavy spheres each of mass 100 kg and radius 0.1 m are placed 1.0 m apart on a horizontal table. What is the gravitational field and potential at the mid point of the line joiningthe centres of the spheres ? Take G=`6.67xx10^(-11)Nm^(2)Kg^(-2)`.

Two heavy sphere each of mass 100 kg and radius 0.10 m are placed 1.0 m apart on a horizontal table. What is the gravitational field and potential at the mid point of the line joining the centres of the sphere? Is an object placed at that point in equilibrium? If so, is the equilbrium stable or unstable.

Two heavy spheres each of mass 100kg and radius 0.1m are placed 1m apart on a horizontal table. What is the gravitationl field and potential at the mid point of the line joining their centres. The gravitational potential difference between the surface of a planet and a point 20m above it is 16J//kg . Calculate the workdone in moving a 2kg mass by 8m on a slope of 60^@ from the horizontal.
