What is the electric force between two protons that each have a charge of 1.6 * 10 -19 if they are 1.50 m apart? (1 m = 1 * 10 -6 m) Is this force

What is the electric force between two protons that each have a charge of 1.6 * 10-19 if they are 1.50 μm apart?

(1 μm = 1 * 10-6 m)

Is this force attractive or repulsive?

Please show the correct scientific notation and significant figures.

Thank you!
