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. Fel = μA 2.7.10 6 Submit N Previous Answers Request Answer ? X Incorrect; Try Again; 5 attempts remaining Use the equation Fel = K(Q₁ Q₂/d²) to find the electrostatic force between the two particles. Q₁ and Q2 are the charges on the particles (charge of a proton here), and d is the distance of separation. The constant is given in the introduction and has the units Nm²/C². This means that the distance must be converted from picometers to meters using the relation 1 pm = 1 × 10¯ m. -12
