Answer 1

Answer:

Scalar form of the law

The constant ke is called Coulomb's constant and is equal to 14πε0, where ε0 is the electric constant; ke = 8.988×109 N⋅m2⋅C−2. If the product q1q2 is positive, the force between the two charges is repulsive; if the product is negative, the force between them is attractive.

Answer 2

Answer:

f= 1/€04¶ ×q1q2/r^2
