Voltage = Power/Charge.

So, v = 60/15 = 4 v.

Voltage = (Work done/Charge).

Energy is ability to do work.

So, Voltage = (w/q).

= (E/q).
= 60/15.
= 4 volt.

Energy = 1/2(CV^2).

C = Charge.
V = Voltage.

V^2 = 2E/C.
V^2 = (40/3).

V = 3.6.
V = 4.

E = q*v.
60 = 15.v.
v = 60/15 = 4V.

Energy = qV.

Since electric field strength is E = F/q = V/d.

With V = voltage, d = distance between charged plates.

Fd = qV.

Energy = qv.

Energy = C*V.

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

I think your relation give the above problem right.

RAFIQUE ANSARI said:   1 decade ago
V = J/C.
= 60/15.
= 4.

KUMAR SHANU said:   1 decade ago
Since Q = CV given that Q = 60 and C = 15.

So answer is V = Q/C = 60/15 = 4v.

Energy = Charge/Voltage.

= 60/15 = 4.
