Answer:
V = 72000 volts
Explanation:
calculates the electric potential of a point B that is 75cm from a positive charge q = 9 × 10-6c
Given that,
Electric charge, 
We need to find the electric potential of a point B that is 75 cm from this charge. The formula for the electric potential is given by :

So, the electric potential is equal to 72000 Volts.
