Question

What is the force of gravity between two 50.0kg masses that are separated by 0.300m?3.71x10-8N5.59x10-7N2.78x104N1.85x10-6N

Answer 1

We will have the following:

`\begin{gathered} F=G(m_1m_2)/(r^2)\Rightarrow F=((6.67\ast10^(-11)m^3\ast kg^(-1)\ast s^(-2))(50kg)(50kg))/((0.3m)^2) \\ \\ \Rightarrow F=1.852777778...\ast10^(-6)N\Rightarrow F\approx1.85\ast10^(-6)N \end{gathered}`

So, the force is approximately 1.85*10^-6 N.
