Answer:
both charges will have different potential energies that will depend upon the charge magnitude.
Step-by-step explanation:
It is given that both the charges are on the same equipotential line which means the potential V at which the two charges are is same.
Now the potential energy of a charge at potential V is given by
q×V where q is the charge value
Thus Higher the charge value for a given value of potential , higher will be the potential energy
Thus the larger charge will have higher potential energy and not the same.
