e Secure l https://uab.instructure.orn/coursesi47 19:01 nake DQuestion 9 10 pts What is the magnitude (in N/C) and direction of an electric field that exerts a2 x 10"'N upwad force on a-25 charge? lC 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 28 DQuestion 10 10 pts The classic Millikan oil drop experiment was the first to obtain an accurate measurement of the charge on an electron. In it, oil drops were suspended against the gravitational force by a vertical electric field Consider an oil drop with a weight of 2.9 x 101"N, if the drop has a single excess electron, find the magnitude (in N/C) of the electric field needed to balance its weight. Your should round your answer to an integer, indicate only the number, do not include the unit. - Summary Sheet T..dooxElectric Charge an .pdt doc A

Explanation / Answer

given that

F = 2*10-5 N

q = -2.5*10-6 C

we know that

E = F/q = 2*10-5/-2.5*10-6

E = - 8 N/C

negative sign shows the direction downward .
