Answer:
Explanation:
The problem can be solved easily, because the relationship between intensities 
and 
at distances 
and 
respectively can be written as:
Where:
In this case:
Solving for
Two or more velocities add by vector sum.
In fact, velocity is a vector, with its own intensity, direction and verse. Therefore, we cannot simply add two velocities by algebraic sum, but we need to decompose them on two axes (if we are in a 2D-plane) and calculate the resultant on each axis, and then calculate the total resultant of the two vectors, which will have its intensity, direction and verse.
Answer:
D
Explanation:
as one burns then all stop simple

Electric force varies directly with the magnitude of each charge, and inversely with the distance between the charges.
but for short....
electrical force depends on the charge and distance
