Question

calculate the force of electrostatic attraction between s proton and electron separate by a distance of 8×10-14 m​

Answer 1

hope this solution will help you

Answer 2

F=k × q1×q2/r^2.

than, k= 9×10^9Nm^2/C^2.

q1 and q2 are the charges of the bodies in coulomb .

hence, F=(1.609^-19)^2 × 9× 10^9/ (8×10^-14)^2

F= 0.03640 N
