Answer:
A body is said to be moving with uniform speed, if it covers equal distances in equal intervals of time. ...
Answer:
The magnitude of each charge is 
Explanation:
Suppose the two point charges are separated by 6 cm. The attractive force between them is 20 N.
We need to calculate the magnitude of each charge
Using formula of force

Where, q = charge
r = separation
Put the value into the formula




Hence, The magnitude of each charge is 
If the velocity is constant, then the position/time graph has a constant slope, meaning a straight line.
The slope may be any constant value ... positive, negative, or zero.
-∞ < slope < +∞
Answer:
Both forces act along the line joining the objects like masses or charges. And both forces are inversely proportional to the square of the distance between the objects, this is known as the inverse-square law.
