We know Q = CV.
V = Q/C.
V= 60/15 = 4V.
V = Q/C.
V= 60/15 = 4V.

An ideal capacitor is wholly characterized by a constant capacitance C, defined as the ratio of charge Q on each conductor to the voltage V between them
c = q/v.
So rearrange above equation,
v = q/c.
v = 60/15.
v = 4v.
c = q/v.
So rearrange above equation,
v = q/c.
v = 60/15.
v = 4v.

The problem is for only one charge, hence capacitor fundamental can't be applied, therefore simple energy relation can be used here i.e.
E = q*v.
=> v = E/q.
v = 60/15.
v = 4V.
E = q*v.
=> v = E/q.
v = 60/15.
v = 4V.

Q = 15c, and E = 60j given,
P = V*I.
dE/dt = P = V*I.
I = dQ/dt.
E = V*Q.
V = E/Q = 60/15 = 4.
P = V*I.
dE/dt = P = V*I.
I = dQ/dt.
E = V*Q.
V = E/Q = 60/15 = 4.

Condition 1: Energy = Charge * Voltage.
Then,
Voltage = Energy by Charge.
Then,
Voltage = Energy by Charge.

Voltage is equal to work per unit charge.
V = w/q.
V = 60/15 = 4.
V = w/q.
V = 60/15 = 4.

The potential energy is a form of energy and the potential (and therefore voltage, when differences are taken) is defined as the potential energy (or potential energy difference) per unit charge, V=E/Q.
V = 60/15 = 4.
V = 60/15 = 4.

E = Q*V.
60 = 15*V.
V = 60/15.
V = 4V.
60 = 15*V.
V = 60/15.
V = 4V.

60/15 = 4 Volts.
It is easier to understand if you say the charge flows during a time t, then the current is 15/t Amps. The power available is 60/t Watts. Watts = Volts * Amps
60/t = V * 15/t.
V = 4.

V = voltage.
E = energy.
C = charge.
As we know that E=C*V.
V = E/c.
V = 60/15.
V = 4.
E = energy.
C = charge.
As we know that E=C*V.
V = E/c.
V = 60/15.
V = 4.
