Answer:
The direction of the field is downward, and negatively charged particles will experience an upwards force due to the field.
F = N e E where E is the value of the field and N e the charge Q
M g = N e E and M g is the weight of the drop
N = M g / (e E)
N = 1.1E-4 * 9.8 / (1.6E-19 * 370) = 1.1 * 9.8 / (1.6 * 370) * E15 = 1.82E13
.00011 kg is a very large drop
Q = N e = M g / E = .00011 * 9.8 / 370 = 2.91E-6 Coulombs
Check: N = Q / e = 2.91E-6 / 1.6E-19 = 1.82E13 electrons
OPTION C is the correct answer.
Answer:

Explanation:
When two cars collide then the momentum of two cars will remains conserved
- Mass of two cars = 100 kg
-
Speed of car B = - 10 m/s
-
After collision the speed of car B = +8 m/s
By momentum conservation equation


Science can be used to look for other renewable resources than mining for coal
