Answer:
Upward
Explanation:
For charged particles immersed in an electric field:
- if the particle is positively charged, the direction of the force is the same as the direction of the electric field
- if the particle is negatively charged, the direction of the force is opposite to the direction of the electric field
In this problem, we have an electron - so a negatively charged particle - so the direction of the force is opposite to that of the electric field.
Since the electric field is directed downward, therefore, the electric force on the electron will be upward.
Answer:
weight
Explanation:
The weight of an object is the force of gravity on the object and may be defined as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton. Density is mass/volume.
D) Kilograms is the standard unit of mass
