4. In a theory section of a paper, it was stated,: \'\'Since both work and charge are scalar quantities, potential difference is also a scalar quantity. The potential near an isolated positive charge IS positive, while that near an isolated negative charge is negative.\" What is the meaning of negative work?

Solution

Work = charge*potential difference

By the above theory if work is negative it means,

1. In the presence of a negative charge, work done will be negative and work will be done by the positive charge if we bring the positive charge towards the negative (attraction)

Or

2. Vice versa

In the presence of a positive charge, work done will be negative and work will be done by the negative charge if we bring the negative charge towards the positive (attraction)
