Answer:
Doubled
Explanation:
F = 1.8 x 10^-6 N, q1 = q2
The force between the two charges is directly proportional to the product of two charges and inversely proportional to the square of distance between them.
Now one of the charge is doubled but the distance remains same so the force between the two charges becomes doubled.
Answer:
200 W
Explanation:
The power is given by the ratio between the amount of work done and the time taken to perform the work:
where in this problem we have
W = 2600 J is the work done
t = 13 s is the time taken to do the work
Substituting the numbers into the equation, we find
