Equals variation in position over variation in time, here’s the formula hope it helps :)
You can pour as much water into it as you feel like. But if you pour in more than 440 liters, it'll reach over the top and overflow onto the floor.
Answer:
d. 0V
Explanation:
The magnitude of four point charges are +3q, -q, +2q and -4q. I think you forget to mention the signs.
As we know that the potential due to the point charge that has traveled the distance d can be represented mathematically as,
= 1/4λε = 9× Nm²/C²
Now as it is mentioned in the question that all four charges are arranged in the corners of a square so there distance from the center is same. We can rewrite the above potential equation as follows.
(1)
We can find out d by the pythagoras theorem, as we are dealing with square so d is a semi diagonal.
by putting all values in equation (1)
V =
V = 0V
Newton first law state that anything in motion or rest will remain in motion or in rest until an external force is applied
Newton third law of motion state that every action have equal and opposite reaction
