1. ## Physics Calculator

Need help putting this in my scientific calculator (6.67x10-11)(20)(20)/(0.5)2

You could simplify it as:

$\frac{6.67\times10^{-11}\cdot20\cdot20}{\left(\frac{1}{2} \right)^2}=\frac{400}{\frac{1}{4}}\left(6.67\times 10^{-11} \right)=$

$\left(1.6\times10^3 \right)\left(6.67\times10^{-11} \right)=10.672\times10^{-8}=1.0672\times10^{-7}$
