The charge is obtained as 1.5 * 10^-5 C.

What is potential?

The electric potential is the work done in moving a unit charge from one point to another.

Now we have;

W = -QdV

W = Work done in joules

Q = charge

dV = voltage change

Hence;

4.3×10−4 =- Q( 120 - 400)

Q = 4.3×10−4/280

Q = 1.5 * 10^-5 C
