Answer:
slope is -2
Step-by-step explanation:
1. go to geogebra.org/classic (this is a graphing calculator)
2. enter your two points by using the second button on the top of the screen
3. connect a line from one point to the other using the 3rd button on the top of the screen
4. click on the line and it shall tell you the equation, including the slope :O))))
the slope is -2 and the equation is y = -2x + 18
We are given
total number of particles =4
and
total sum of charge=-36
Since, all the particles have the same charge
and total charge is negative
so, charge on each particle must be negative
now, we can use formula to find change on each particle
charge on each particle = (total sum of charge)/( total number of particles)
now, we can plug values
and we get
The charge on each particle is
units..............Answer
