The question extends beyond what I already know.
The question makes me curious.
Answer:F=4F
Explanation: Columbs law states that The force between the two point charges is directly proportional to the product of charges and inversely proportional to the square of distance between them
Force between the two charges is given by
F=K*q1*q2/r^2
if one charge become 4 times, new force is,
F=4(K*q1*q2)/r^2
F=4F
Where q1 and q2 are the point charges
r is the distance between the two charges
K is a constant of proportion called electrostatic force
Answer:
![\sf Proof \ below](https://tex.z-dn.net/?f=%5Csf%20Proof%20%5C%20below)
Explanation:
We know that acceleration is change in velocity over time.
![\sf a=\frac{\triangle v}{t}](https://tex.z-dn.net/?f=%5Csf%20a%3D%5Cfrac%7B%5Ctriangle%20v%7D%7Bt%7D)
![\sf a=\frac{v-u}{t}](https://tex.z-dn.net/?f=%5Csf%20a%3D%5Cfrac%7Bv-u%7D%7Bt%7D)
v is the final velocity and u is the initial velocity.
Solve for v.
Multiply both sides by t.
![\sf at=v-u](https://tex.z-dn.net/?f=%5Csf%20at%3Dv-u)
Add u to both sides.
![\sf at + u=v](https://tex.z-dn.net/?f=%5Csf%20at%20%2B%20u%3Dv)
-- If 2,000 newtons of force were applied through a distance of 1,000 meters,
then 2,000,000 newton-meters = 2,000,000 joules of work were done.
-- 45 minutes = (45 x 60) = 2,700 seconds
-- Power = (work) / (time) = (2,000,000 j) / (2,700 s) = <u>740.74 watts</u>
Interestingly, that's almost exactly 1 horsepower. (0.99295... of 746 watts)
