Answer:
q = 1
Explanation:
Given that,
No. of electrons = -12
No. of protons = 13
We need to find the net charge on the balloon. We know that net charge is equal to the sum of proton and the electrons such that,
Net charge = No. of electrons + no. of protons
= -12 + 13
= 1
So, the net charge is equal to 1.
