Calculate the average net force.

MrRa [10]

Answer:

<h2>given</h2>

mass = 3950 kg

speed= 25m/ sec

time= 10.5 sec

force

<h2>Solution</h2>

<h3>☄️Formula of force </h3>

$\fbox{f = m.a}$

To find the force we need to find the Acceleration first.

accleration= change in Velocity/time

accleration= 25/10.5

accleration= 2.38 m/sec²

put the value of accleration in the formula of force

force = Mass . accleration

force = 3950 x 2.38

<h3>☄️force = 9,401 Newton</h3>

The original magnitude of the force on the Q charge was F; what is the magnitude of the force on the Q charge now?

Otrada [13]

Complete Question:

Two small objects each with a net charge of Q (where Q is a positive number) exert a force of magnitude "F" on each other. We

replace one of the objects with another whose net charge is 4Q. The original magnitude of the force on the Q charge was "F"; what is the magnitude of the force on the Q charge now?

Answer:

4 F₀

Explanation:

Assuming that we can treat to both objects as point charges, we can find the force "F" that one charge exerts upon the other applying Coulomb´s law, as follows:

F₀ = K*Q₀² / r₁₂²

If we replace one of the charges by one with a 4Q₀ charge, the new value of F will be as follows:

F₁ = K*Q₀*4Q₀ / r₁₂² =( K*Q₀² / r₁₂²)* 4 = 4* F₀

This value is reasonable, as the electrostatic force is a linear - type one, so it is possible to use the superposition principle (we can get the force exerted by one charge on another without considering the ones due to another charges)
