Three object net gravitational field problem

Click For Summary
SUMMARY

The discussion centers on calculating the gravitational force and acceleration on a 5 kg mass placed at point K due to two 10 kg masses located at (0,0) and (2,0) on an x-y coordinate plane. The gravitational force formula used is Fg = (G * m1 * m2) / r^2, where G is the gravitational constant. Participants clarified that the negative sign in the formula is unnecessary, as the direction of the force is determined by the coordinate system. The user successfully solved the problem after receiving guidance on finding the x/y components of the gravitational force.

PREREQUISITES

Homework Statement



Two 10 kg masses are placed on an x-y coordinate plane measured in meters. the first mass is at position (0,0) and the second at (2,0). that's the first part of the problem the second part is: if an additional 5 kg mass is placed at the point K, calculate the gravitational force and acceleration exerted on the mass due to this net field.

(there are two answers one for each part)

Homework Equations



i tried Fg= (-G(m1)(m2))/r^2 (not sure if its correct)
I don't know where to start can someone help. thanks

Your equation for the force of gravity is correct, although I don't think the "-" is necessary, the direction of the force depends only on your chosen co-ordinate system.
You will want to start by finding the x/y components of the gravitational force.
 
thanks for the response. i figured out the problem. but thanks
