Answer:
80 volt
Step-by-step explanation:
We have given charge = 0.4 C
Work done = 32 J
We have to calculate the voltage required to separate the charge
Work done is equal to the multiplication of charge and voltage that W = charge ×voltage =QV
So
![32=0.4* V](https://img.qammunity.org/2020/formulas/physics/college/x50r6dt15yuf2i5y5n0mjb3o4s2q0m42l5.png)
![V=(32)/(0.4)=80volt](https://img.qammunity.org/2020/formulas/physics/college/rpg5nnxk19vkfv2a0l0z5ncoku30zvhl9n.png)
So 80 volt is required to seprate the two charge of 0.4 C
