Problem

3\,\text{C}

charge is first moved across a potential difference of

4\,\text{V}

and then across an additional

6\,\text{V}

. Afterwards, a

2\,\text{C}

charge is moved directly through a potential difference of

10\,\text{V}

. What is the total work done in these two moves? a)

60\,\text{J}

38\,\text{J}

50\,\text{J}
