At a distance of 2.0 m. from a +8.0 x 10^-6 C charge, the magnitude and direction of the electric field will be?

1 answer

Coulomb's law:
F = k q1 q2/r^2
E = force on unit charge
E = F/1 = k q /r^2

= 9*10^9 * 8*10^-6 /4

1.8 *10^4 Newtons/Coulomb
like charges repel so in direction away from positive charge
