Answered

A negative charge of -200 C and a positive charge of 800 C are separated by 0.3 m. What is the force between the two charges? Is this force attractive or repulsive?



Answer :

The electric force between the two charges is 1.6 x 10¹⁶ N  and it attractive.

What is electric force between the charges?

The electric force between the charges is determined by applying Coulomb's law of electrostatic force as shown below.

F = kq₁q₂/r²

where;

  • r is the distance between the charges
  • k is coulomb's constant
  • F is the force between the charges

F = (9 x 10⁹ x 200 x 800) / (0.3²)

F = 1.6 x 10¹⁶ N

Thus, the electric force between the two charges is 1.6 x 10¹⁶ N  and it attractive.
