What is the value of the charge that experiences a force of 2.4 × 10–3 n in an electric field of 6.8 × 10–5 n/c? 1.6 × 10–7 c 2.5 × 10–3 c 2.8 × 10–3 c 3.5 × 101 c

An object of charge q immersed in an electric field of intensity E experiences an electric force of magnitude F equal to


In our problem, the force exerted on the charge is 

while the intensity of the electric field is


Therefore, we can find the charge by re-arranging the previous equation and by using these data:


So, the correct answer is
