A particle of charge 2.3 ✕ 10−8 C experiences an upward force of magnitude 4.6 ✕ 10−6 N when it is placed in a particular point in an electric field. (Indicate the direction with the signs of your answers. Assume that the positive direction is upward.)
(a) What is the electric field (in N/C) at that point? N/C
(b) If a charge q = −1.1 ✕ 10−8 C is placed there, what is the force (in N) on it? N
