${\mathbf{F}}_{\mathbf{el}}\mathbf{}\mathbf{=}\mathbf{}\mathbf{k}\frac{\mathbf{\left(}{\mathbf{Q}}_{\mathbf{1}}{\mathbf{Q}}_{\mathbf{2}}\mathbf{\right)}}{{\mathbf{d}}^{\mathbf{2}}}$

You may want to reference (Pages 165 - 166) Section 5.1 while completing this problem.

Use the following equations:

- F
_{el}= k(Q_{1}Q_{2}/d^{2}), where k = 8.99 x 10^{9}N m^{2}/ C^{2} - F
_{g}= G(m_{1}m_{2}/d^{2}), where G (gravitational constant) = 6.67410^{-11}N m^{2}/ kg^{2}

Calculate the electrostatic force of repulsion for two protons separated by 93.0 pm. The charge of a proton is q = 1.6 x 10^{-19} C. Express your answer to two significant figures and include the appropriate units
