1. in an experiment, a positively charged oil droplet weighing 6.5 x 10-15 n is held stationary
by a vertical electric field. if the electric field strength is 5.3 x 103 n/c, what is the charge
on the oil droplet?
a. 1.2 x 10-18 c
b. 3.4 x 10-11c
c
. 4.1. 104c
d. 8.2 x 1017 c

i think the answer is a, hope this : )

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

0.93xc=0.93x3x10^8m/s

2.54cm is 1 inch
