Answer:
the answers the correct one is case B. The field decreases the external field
Explanation:
We place the bar in an area of space with an electric field, generated by a series of positive and negative charges. Negative charges inside the bar are attracted by positive charges, and positive charges are attracted by negative external charges. As the electric field has direction of the positive charges towards the negative ones the field inside the bar is contrary to the external field
When reviewing the answers the correct one is case B. The field decreases the external field
E_net = E_ext - E_int

Answer:
17.78 m/s
Explanation:
Average speed is found by simply dividing the distance travelled by the time that it took to finish the trip. It's measured in meters per second (m/s), so first convert the quantities.
1 km = 1000 m, so 16 km is 16000 m
0.25 hours is 15 minutes. Since 1 minute is 60 seconds, then 15 minutes must be 900 seconds.
Thus:
average speed = total distance/total time = 16000 m / 900 s = 17.78 m/s
Hope this helps!

More massive attacking objects speed slows down and it transfer its some kinetic energy to less massive target objects whereas less massive target objects starts its motion
