Question

State Coulomb’s Law? Derive Electric field intensity expression
using Coulomb’s law

Answer 1

coloumbs law

force of attraction or repeltion between two points charges is

a) directly proportional to the product (q1,q2)of two chaarges and

b) inversely proportional to the square of the distance (r) between them

mathematical formula :F=q1q2/r²
