3 questions about Gravity equation

1. Three particles each with a mass of 1 kg are at the vertices of an equilateral triangle whose sides are 1 m long. How large is the gravitational force experienced by each point particle (in G)?

Solution

The magnitude of the gravitational force experienced by one of the particles.

F_{12} = G (m_{1})(m_{2}) / r^{2 }= G (1)(1) / 1^{2 }= G/1 = G

F_{13} = G (m_{1})(m_{3}) / r^{2 }= G (1)(1) / 1^{2 }= G/1 = G

Resultant gravitational force at point 1:
