Answer: The electric potential midway between them is -5.64 × 10^4 V
Explanation:
Electric potential is measured in volts or joules per coulomb. It is the amount of work required to move a charge from a reference point to a specific point inside the field.
Electric potential V = Σkq/r
k = coulomb's constant = 9.0x10^9 N-m^2/C^2
q1 = +3.21 × 10^-6 C
q2 = -6.75 × 10^-6 C
r = 1.13/2 = 0.565m
V = kq1/r + kq2/r = (k/r)(q1 + q2)
Substituting the values;
V = (9.0x10^9/0.565)(3.21 - 6.75) × 10^-6
V = -56389.3805309 Volt
V = -5.64 × 10^4 volts

There are numerous information's already given in the question. Based on those information's the answer can be easily deduced.
Since temperature is inversely proportional to volume, so
T = k/V
30 = k/90
k = 2700
When the volume of the gas is 18 cm^3, then
T = 2700/18
= 150 degree centigrade.
I hope that this is the answer that you were looking for and the answer has come to your desired help.
The final velocity upon reaching its maximum height of 500 m will be 0 m/s.
Applying:
2as = v² - u², and taking the upward direction to be positive, the acceleration will be -9.81 m/s²
2 x 500 x -9.81 = -u²
u = 99.0 m/s
