From equation of motion v^2 = u^2 +2aS
Hence, the final velocity is 40 m/s.

In physical science, tension can be described as the motion that applies a pulling force that is transmitted axially through cables, chains, or string. On the other hand, compression is the application of balanced inward forces while extension is the application of balanced outward forces in the same axis through the object.
Answer:
For the force due to electromagnetism we use Coulomb’s inverse square law:
F=keq1q2r2
(where F is the electrostatic force, q1 & q2 are the two charges, r is the distance between them, and Coulomb’s Constant ke=14πϵ0=8.99×109Nm2C−2, where ϵ0 is the permittivity of free space)
r=keq1q2F−−−−−√
r=8.99×109Nm2C−2−1.60×10−19C×−1.60×10−19C1.0N−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−√
r=1.52×10−14m
