Answer:
2 m
Explanation:
The displacement of any body is the shortest distance in an object's path between its initial and final point.
The ball would travel 3 m from the point of throwing then fall down 5 m to the ground. The total distance traveled is 7 m.
The displacement of the ball will be the distance from the point of throwing to the ground i.e., 2 m as it is the shortest distance between the initial and final point of the ball's journey.
Answer:
<em>The total potential (magnitude only) is 11045.45 V</em>
Explanation:
<u>Electric Potential
</u>
The total electric potential at location A is the sum of all four individual potentials produced by the charges, including the sign since the potential is a scalar magnitude that can be computed by

Where k is the Coulomb's constant, q is the charge, and r is the distance from the charge. Let's find the potential of the rightmost charge:

The potential of the leftmost charge is exactly the same as the above because the charges and distances are identical

The potential of the topmost charge is almost equal to the above computed, is only different in the sign:

The bottom charge has double distance and the same charge, thus the potential's magnitude is half the others':

The total electric potential in A is


The total potential (magnitude only) is 11045.45 V
