Answer:
The value of Q is - 8 C
Explanation:
Given;
the magnitude of first charge = 2 C
position of the first charge = 0
_ (2m) 0(+2C) +(2m)(Q)
------------------------------------------------------------------------------------
E₁ --------------------------------->
<------------------------------------------------------------------ E₂
E₁ and E₂ are equal in magnitude but opposite in direction
| E₂ | = | E₁ |
Thus, since E₂ is opposite in direction to E₁, the Q = - 8 C
The momentum of a moving object is given by:
where m is the mass of the object and v its speed.
In this problem, the ball has a mass of
and its momentum is 
, so we can rearrange the previous equation to find the speed of the ball:
where m is the mass of the object and v its speed.
In this problem, the ball has a mass of
