Answer:
Explanation:
Generally from kinematics equations we have that
Here u is the initial velocity of the rock and the value is 0 m/s given that there was no information that it was in motion before the fall
substituting 1.43 s for t and for g we have that
=>
The negative sign show that the displacement is in the direction of the negative y-axis
The magnitude of the electrical force between q2 and q3 is given as a ratio between the product of their charges and the square of the distance of separation.
<h3>What is the magnitude of electrical forces between two charges?</h3>The magnitude of the electrical force between two charges refers to the attractive or repulsive forces that exists between two charges separated by a given distance in an electric field.
The magnitude of the electrical force, F between the two charges q2 and q3 is given be my the formula below
Therefore, the magnitude of the electrical force between q2 and q3 is given as a ratio between the product of their charges and the square of the distance of separation.
