PRACTICE ANOTHE

Three objects of equal mass $m_1=m_2=m_3=2\mathrm{.}70kg$ are located on the vertices of an equilateral triangle of length $d=2\mathrm{.}90m.$ A fourth mass $m_4=15\mathrm{.}5kg$ is at the center of the triangle. What is the net gravitational force on the mass $m_1$ that is at the origin? Express your answer in vector form.

vec$(F{)}_{\text{n}\text{e}\text{t}}=$

$q,$

Review the vector form of the gravitational law. What is the direction of the unit vector for each force acting on the mass located at the origin? N
