Expert Solution
Step 1
Since we answer up to one question, we will answer the first question only. Please resubmit the question and specify the other question you would like to get answered.
Given: The value of the two charge Q is .
To determine: The work required to move a charge q of from point A to B.
The figure shows the distance between the charges to point A and B
The distance between A and C is calculated using Pythagoras rule,
Similarly value of AD is also 5 m.
The distance C and B is
Similarly the distance between DB is 6.71 m.
The potential is given as
where V is the potential, k is the constant, value of k is and r is the distance.
