The strength of the electric field on the point charge at this distance is 4,000 N/C.

What is the electric field strength of the point charge?

The electric field strength of the point charge is calculated as follows;

E = force / charge

E = kq/r²

where;

  • k is coulomb's constant
  • q is the charge magnitude
  • r is the distance of the charge

E = (9 x 10⁹ x 4 x 10⁻⁶)/(3²)

E = 4,000 N/C

Thus, the strength of the electric field on the point charge at this distance is 4,000 N/C.
