Question

Question 9 10 pts What is the magnitude (in N/C) and direction of an electric field that exerts a 2 x 105 N upward force on a -1.5 μC charge? luC 106c Indicate direction with a positive or a negative value. Keep in mind that a positive vector is directed upwards and a negative vector is directed downwards on the y axis. On the x axis, a positive vector is directed to the right and a negative vector is directed to the left. Your answer should be a positive or a negative number with two decimal places, do not include the unit.

Answer 1

F=qE

Charge (q) = -1.5x10^-6C

Force F=2x10^-5N upward

F=qE

2x10^-5 = -1.5x10^-6 E

E= -13.33N/c downward Ans.
