help with b and c please

Part B Calculate the gravitational force of attraction for two protons separated by 87.0 pm. The mass of a proton is mp = 1.673 x 10-27 kg. Express your answer using two significant figures. Ivo A20 ? F N Submit Request Answer Part C It allowed to move, will the protons bo repelled or attracted to one another? Electrostatic repulsion is much greater than gravitational attraction and the protons move together. Electrostatic repulsion is much greater than gravitational attraction and the protons move apart Electrostatic repulsion is much less than gravitational attraction and the protons move together Electrostatic repulsion is much less than gravitational attraction and the protons move apart Submit Request Answer Provide Feedback Use the following equations: Fa=r(Q.Qz/d%), where x = 8.99 10N-m/C F = G(mm/dl), where G (gravitational constant) = 6.674 X 10-11 N. m/kg . Part A Calculate the electrostatic force of ropulsion for two protons separated by 87.0 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. Fa= 3.0x10-N Previous Answers
