1.	Four identical point masses each equal to M are placed at the four corners of a square of side a. Calculate the force of attraction or another point of mass M1 kept at the centre of the square
Answer» F(Net) = (4 x G x M x M1) / (r^2) Since the GIVEN masses are ideal POINT masses and do not exhibit any electrical characters, we are free to use Newton’s LAW of Gravity. The force of attraction between the 4 bodies placed at the BOUNDARY and the lone mass placed at the centre can be given by the application of the following formula 4 times: F = (G x M x M1) / (r^2) Where, G is universal gravitational constant and r is the distance between the central mass and boundary mass. Since each mass exerts the above force, the combined force FELT by the central mass will be: F(Net) = (4 x G x M x M1) / (r^2)

Answer»

F(Net) = (4 x G x M x M1) / (r^2)

Since the GIVEN masses are ideal POINT masses and do not exhibit any electrical characters, we are free to use Newton’s LAW of Gravity.

The force of attraction between the 4 bodies placed at the BOUNDARY and the lone mass placed at the centre can be given by the application of the following formula 4 times:

F = (G x M x M1) / (r^2)

Where, G is universal gravitational constant and r is the distance between the central mass and boundary mass.

Since each mass exerts the above force, the combined force FELT by the central mass will be:

F(Net) = (4 x G x M x M1) / (r^2)
