Question

If it takes E = 50.1 mJ of energy to separate Q = 1.51 C of charge, what is the resultant voltage?

Answer 1

Answer:

3.3V

Explanation:

We are given that

Energy ,E=50.1 mJ=$50.1\times 10^{-3}J$

1mJ=$10^{-3}J$

Charge ,Q=1.51 C

We have to find the resultant voltage .

We know that

Voltage=$V=\frac{W}{Q}$

W=Work done

Q=Charge

Work done=E

Therefore, W=$50.1\times 10^{-3}J$

Using the formula

The resultant voltage=$V=\frac{50.1\times 10^{-3}}{1.51}=3.3\times 10^{-2}$V

The resultant voltage=3.3V
