Determine the linear equation for P in terms of h
First, we calculate the slope/rate (m);
The following formula is used:
Substitute values for P's and h's
Multiply by 1000/1000
The equation is then calculated using:
Substitute values for m, h1 and P1
Make P the subject
<em>The above is the required linear equation</em>
Answer:
The objects have opposite charges.
Explanation:
The object when released are moving towards each other simply because they attract each other.
- According to coulombs law of charges, like charges repel and will move away from one another.
- Unlike charges attracts and moves towards one another
- Since the objects are coming towards each other, they are of opposite charges.
