A ball has an electric charge of +1.5 × 10-9 coulombs. At what distance from the ball's center is the electric field strength equal to 5.8 × 105 newtons/coulomb?
F = kq1q2/r2 Where, F - Coulomb Force k - constant value which is equal to 8.98 × 10^9 newton square metre per square coulomb q1 and q2 - two electric charges r - distance.
