Answer:
432 units
Explanation:
Let the charges be q and Q separated by a distance r. The electrostatic force , F = kqQ/r² = 72 units. If q = 2q and Q = 3Q, then the new electrostatic force is
F = k × 2q × 3Q/r² = 6kqQ/r² = 6 × 72 = 432 units

Required
By how much does her GPA increases
To do this, we simply calculate the potential energy.
Where
At the ground level, the height is 0
i.e. 
So:
At:
So, we have:
Calculate the difference
<em>Hence, it increases by 1000 joules</em>
