BLUE PEARL said:Two stars of equal mass M move with constant speed V in a circular orbital of radius R about their common center of mass .What is the net force on each star?the answer to this question was net force=GM^2/4R^2 .I want to ask that why net force not equal to zero although it is in translational equilibrium?
Any help in this regard would be appreciated...Thank You in anticipation
Net force is the overall force acting on an object, taking into account the magnitude and direction of all individual forces.
When net force is equal to 0, it means that all individual forces acting on an object are balanced and there is no acceleration in any direction.
Net force is calculated by adding together all the individual forces acting on an object, taking into account their direction and magnitude.
This equation shows the relationship between net force and the gravitational force between two objects, where G is the universal gravitational constant, M is the mass of one object, and R is the distance between the two objects.
Yes, the net force can be greater than GM^2/4R^2 if there are other forces acting on the object in addition to the gravitational force, such as friction or air resistance.
